TerraPower is a company. Bill Gates is more than just the founder of Microsoft. He is also a leader in the fight against climate change. In 2008, the man decided to step down as the company’s leader. He is still on the board of directors, but he has spent the last few years working on investments that could prevent a future crisis that is worse than the one we are in now.
TerraPower
Bill Gates started TerraPower in 2006, which was two years before he left Microsoft as CEO. The United States Department of Energy and the Los Alamos National Laboratory, which is one of the largest technological institutions in the world and does research in many fields, including renewable energy and nuclear fusion, two key parts of the TerraPower vision, provide some of the money for the company.
In general, it is an engineering, development, and design company for nuclear reactors. Its goal is to create a type of nuclear reactor called a Traveling Wave Reactor, or TWR, which could use nuclear transmutation to turn fertilizer into fuel. These are different from other kinds of reactors because they can use the fuel without having to do things like reprocessing or enriching the uranium.
In the past few years, experts have looked at the possibility of using nuclear energy to stop climate change by changing the way we use fuel. Billionaire Bill Gates is a big fan of this kind of technology, so he has a lot of faith in this company and thinks it will be able to change the world and even save it in the future.
TerraPower has been able to make deals that have brought in investments worth millions of dollars. In 2020, the Department of Energy chose him to get a $4 billion grant over 5–7 years to build a demonstration of one of his designs. This design uses liquid sodium, which is then turned into molten salt that can be used as energy.
In August of this year, an energy conglomerate in South Korea, which is one of the country’s biggest energy providers, gave $750 million to the company. TerraPower has also sold some of its prototypes to China in the past.
All of the money is used to develop new ways to use nuclear energy. On the other hand, the company also works on nuclear medicine research.
But not all of it comes from other countries. Bill Gates usually puts his own money into this company, which is one of the most important things he has done to fight climate change. In the same way, men tend to put their money into other companies that make green energy or technologies that could change the industry in the future. He also runs the Bill and Melinda Gates Foundation, which gives money to organizations that do this kind of research.
This Samsung Galaxy Z Fold 4 Review shows us that as we expected, the main focus of Samsung’s recent presentation was the Galaxy Z Fold 4. Not only is it the only brand that has taken the idea of foldable phones seriously, but its highly rated phones have also really nailed it. As shown by the Fold 3, we had high hopes for this update. What they gave us wasn’t the big jump we were hoping for, but it was enough to keep us interested in these devices.
Overall, the new Fold 4 is a good and attractive addition to the lineup. It’s not too different from the Fold 3, which, to be fair, looks pretty hard to beat (Bill Gates chose it). Here, we’ll tell you what you need to know about this new device and how long you can expect to see it in stores.
Samsung Galaxy Z Fold 4 Review and Specs
The Samsung Galaxy Z Fold 4 looks a bit more elegant and is a bit lighter. When folded, it only gets smaller by a few millimeters. You might not be able to see the change, but it is there. The weight goes down by just over 10 grams, which is great because the Fold 3 is a bit heavy because of how it is made.
Inside, it has a Snapdragon 8 Plus Gen chip with 12GB of RAM and storage that starts at 256GB and goes up to 1TB which is still perfect. It now has a 50-megapixel main camera with an x3 telephoto lens, which is much better than the last one, and the cameras are much easier to use. Now there is a little more space, and even though some people thought you would only have one screen, there is still a space between the two screens.
The cover screen now has a few extra millimeters, which gives you a little more room. The main one is now stronger and protected by ultrathin glass. Both screens are OLED with 120Hz refresh rates, and Samsung’s S Pen, which is sold separately, can be used with both.
During the presentation, they talked about its power and capacity, which they said would be the same as a PC. They also talked about its immersive and long-lasting displays, its night photography, and, of course, its ability to fold.
Those are the most important changes to this phone. However, even though there are no other changes, it will still be a great choice for Samsung fans who want the newest phone. But the best news is that the Fold 3’s price may go down on the market, which could be a great way to try out Samsung’s folding technology and see how the Smartphone works.
As for the presentations, there will now be four colors: Phantom Black, Graygreen, Beige, and a Burgundy that will only be sold on the Samsung site.
Samsung Galaxy Z Fold 4 Price
The Samsung Galaxy Z Fold 4 Review tells us its price starts at $1,799. The price won’t go down because it’s still one of the best high-end phones from that brand.
Atomic clocks and exact astronomical measurements have shown that days are suddenly growing longer, but scientists are unsure of the cause. This has a significant impact on our ability to keep accurate time as well as other modern technologies like GPS.
The length of a day is determined by the Earth’s rotation around its axis, which has been accelerating during the past few decades. Our days have been getting shorter due to this tendency; in fact, in June 2022, we established a record for the shortest day in the last 50 years or so.
Despite this achievement, the continuous acceleration has strangely slowed down after 2020; the cause of this is yet unknown. Days are once again growing longer. While the clocks in our phones say there are exactly 24 hours in a day, the actual time it takes for Earth to complete a single rotation varies ever so slightly. Even earthquakes and storm events can contribute to these changes, which can take place over timescales ranging from millions of years to virtually quickly.
It turns out that a day rarely has exactly 86,400 seconds.
The causes of the shift in Earth’s day length
The moon’s tidal power
Earth’s rotation has slowed down over millions of years as a result of friction brought on by the Moon’s tides. It lengthens each day by 2.3 milliseconds every century as a result of this process. A day on Earth was just approximately 19 hours long a few billion years ago.
Polar ice melting
Another process, which has been operating in the opposite direction for the last 20,000 years, has sped up the rotation of the Earth. Earth’s mantle began gradually sliding toward the poles as the last ice age ended as a result of the polar ice sheets melting, which decreased surface pressure.
Our planet’s spin rate increases when this mass of mantle moves closer to Earth’s axis, just as a ballet dancer spins faster when they draw their arms toward their body — the axis around which they spin. And over the course of a century, this technique cuts each day by around 0.6 milliseconds.
Results of an earthquake
The relationship between the interior and surface of the Earth is also important over decades and longer. The duration of the day can be altered by powerful earthquakes, but usually only slightly. For instance, the magnitude 8.9 Great Thoku Earthquake in Japan in 2011 is thought to have accelerated Earth’s rotation by only 1.8 microseconds.
Climate and Weather
In addition to these significant shifts on a larger scale, weather and climate also have significant effects on Earth’s rotation over shorter timescales, resulting in changes in both directions.
The duration of the day can shift by up to a millisecond in either direction as a result of the biweekly and monthly tidal cycles, which move mass around the planet. In length-of-day records for durations as long as 18.6 years, we can observe tidal changes. A significant influence comes from the motion of our atmosphere, and ocean currents also have an impact. Additional changes result from seasonal snow cover, rainfall, or groundwater extraction.
Why is Earth suddenly slowing down?
We have had extremely accurate estimates of Earth’s rotational speed since the 1960s, when operators of radio telescopes throughout the planet began to develop methods to simultaneously examine cosmic objects like quasars, a radio source thought to be static and used as a reference point.
These estimates and an atomic clock were compared, and the results showed that the length of the day had been decreasing recently.
Once we eliminate the rotation speed variations caused by the tides and seasonal impacts, a startling revelation emerges. Despite the fact that Earth’s shortest day will occur on June 29 of 2022, the long-term trend appears to have changed since 2020 from shortening to extending. Over the past 50 years, there has never been a change like this.
It’s unclear why this alteration occurred. Even though back-to-back La Nia incidents have happened before, it might be caused by weather system changes. Although the ice sheets’ steady rate of melting hasn’t changed significantly in recent years, there’s a chance that it has risen. Could it be connected to the massive Tonga volcanic explosion that released a great deal of water into the atmosphere? Given that it happened in January 2022, probably not.
The “Chandler wobble,” a little variation in the Earth’s rotating axis with a period of around 430 days, is thought by scientists to be responsible for the planet’s recent, enigmatic change in rotational speed. The wobble has decreased recently, and radio telescope observations reveal that it has as well; the two may be related.
The option that nothing specific has changed on or around Earth is the final one we consider likely. It may simply be that periodic processes and long-term tidal effects are interacting to temporarily alter the Earth’s rotation rate.
The Orion spacecraft and the European service module that are part of NASA’s Artemis I moon mission and its launch date has been set for August 29 from the Kennedy Space Center in Florida.
Artemis I will test the Space Launch System (SLS) megarocket and the Orion spacecraft to make sure they work well before astronauts take a similar trip in a few years, some of them even to the surface of the moon if NASA’s plans for the moon come true.
The upcoming release is the result of a lot of testing and planning over more than a decade. Rick LaBrode, the Artemis 1 principal flight director at NASA’s Johnson Space Center (JSC) in Houston, said live on Friday that his team had worked very hard for a very long time to get to this point.
Artemis I’ll be there for the first launch of the SLS and only the second launch of Orion, which went into orbit around Earth in 2014. If everything goes as planned, the SLS mega rocket will blast through the air on August 29 and reach orbit in only 8.5 minutes. The upper stage of the huge rocket will put Orion into a translunar injection orbit about 80 to 90 minutes after launch.
If Orion launches on August 29, these milestones will be the start of 42 days full of exciting things to do in space. “There’s no time to stop and take a breath. We really started to move, “said Judd Frieling, who was in charge of Artemis 1’s climb and landing for JSC.
As Orion moves toward the Moon, the SLS upper stage will be responsible for sending scientific objects to the Moon and moving itself into an orbit around the sun. Orion will point to a retrograde lunar orbit . She will stay there for a few weeks, and then the gravity of the moon will help her get back to Earth.
On Artemis I, there are three main targets for the spaceship. Each is meant to show resistance. Members of the mission team want Orion to show that it can safely return through Earth’s atmosphere, that it can work reliably in a “flight environment” from launch to splashdown, and that it can keep astronauts safe inside while they recover after coming home.
Activities like taking selfies in front of its solar panels will be used to keep people interested during the long trip. “When we get to the point where we’re really farther than any human-rated spacecraft, farther than any of the Apollo vehicles went, we want to show that to the public,” LaBrode said.
The Orion mission will end with a high-speed re-entry through Earth’s atmosphere, with the goal of splashing down off the coast of San Diego. You will use a parachute to land in the Pacific Ocean, and just before you hit the water, you will do a “landing orientation” move to make sure you hit the waves at the right angle.
There, the power to the vehicle will be turned on for about two hours to see how well Orion keeps astronauts cool. NASA officials said that a US Navy ship will then fish Orion out of the water and bring it back to land.
Artemis 3 to touch down moon surface in 2025
After the mission, SLS and Orion will be looked at for months to make sure they are ready to carry people. According to the current plan, Artemis 2 will send a crew into lunar orbit in 2024, and Artemis 3, which will be the first human landing on the moon since Apollo 17 in 1972, won’t touch down on the surface before 2025.
Throughout the day, our normal human brain performs a wide range of activities and functions. The human brain operating temperature changes throughout the day. According to new research, the normal temperature of the human brain swings significantly more than previously thought, which could indicate good brain function.
According to the study, certain areas of the deep brain can reach temperatures of up to 40 degrees Celsius, though this varies depending on gender, time of day, and other factors. In comparison, the average oral temperature in humans is less than 37 degrees Celsius. According to researchers, this is not an indication of a malfunction, but rather evidence that the brain is functioning normally. Human brain operating temperature studies have previously used data from brain-injured patients in intensive care, where direct brain monitoring is commonly required.
Researchers were recently able to detect brain temperature in healthy people using a brain scanning tool called magnetic resonance spectroscopy (MRS). However, MRS had not previously been used to investigate how human brain operating temperature varies throughout the day, or how one’s ‘body clock’ influences this.
The new study is the first to create a four-dimensional map of healthy human brain temperature. This chart disproves a number of previously held beliefs by displaying how much normal human brain temperature changes by brain area, age, gender, and time of day.
The researchers also examined data from traumatic brain injury patients and discovered that the presence of daily human brain operating temperature cycles is strongly linked to survival. These findings could help with the diagnosis, prognosis, and treatment of brain injuries.
The study’s findings were published in the journal Brain.
According to the report, the researchers “recruited 40 healthy adults (20 males, 20 females, 20–40 years) for brain thermometry using magnetic resonance spectroscopy.” Participants were scanned in the morning, afternoon, and late evening on a single day.
According to the report, healthy participants’ brain temperatures ranged from 36.1 degrees Celsius to 40.9 degrees Celsius.
Female brains were 0.4 degrees Celsius warmer than male brains on average. Because most females were scanned during the post-ovulation phase of their cycle, their brain temperature was about 0.4 degrees Celsius higher than in the pre-ovulation phase. The menstrual cycle was most likely to blame for this disparity.
The most striking discovery, according to Dr. John O’Neill, Group Leader at the MRC Laboratory for Molecular Biology, is that the healthy human brain operating temperature that would be classified as fever elsewhere in the body. Such high temperatures have previously been measured in people with brain injuries, but they were thought to be caused by the injury. The researchers discovered that the temperature of the brain decreases before sleep and rises during the day. There is evidence to suggest that daily variation is linked to long-term brain health, which the researchers intend to investigate further.
The researchers now hope that the 4D brain temperature map can be used as a guide for what a healthy brain should look like. To be truly useful, however, much more data from a much larger group of people is required.
The seven wonders of the ancient world were a collection of outstanding works of architecture and art from the Middle East, North Africa, and southern Europe.
A number of ancient and medieval writers from Europe and the Middle East argued and described what is now known as the world’s seven “wonders” (not all writers used the term “wonder” to describe them). Herodotus, an ancient Greek historian who lived from 484 to 425 B.C., was one of the first to discuss them, and while his writings on the wonders did not survive, they were mentioned in later publications.
The wonders that should be included on the list have been disputed for millennia, with many authors recommending alternative locations. The current list “only became set in the Renaissance,” according to archaeologists Peter Clayton and Martin Price in their book “The Seven Wonders of the Ancient World” (Routledge, 1988).
THE GREAT PYRAMID AT GIZA, EGYPT

The Great Pyramid of Giza is the oldest ancient wonder on the list, as well as the only one that still stands today. It was built over 4,600 years ago as a mausoleum for the ancient Egyptian king Khufu and was the world’s highest structure until Lincoln Cathedral’s central tower in England was completed in 1311.
The Great Pyramid was originally 481 feet (147 meters) tall, but due to the loss of some of its stones, it now stands 455 feet (139 meters) tall. The interior of the pyramid features a network of tunnels that lead to a “great gallery” that ascends to a room with an empty sarcophagus, known as the “king’s chamber.”
Furthermore, the tunnels in the Great Pyramid connect to two further chambers, one of which is frequently referred to as the “queen’s chamber” (though it did not likely house a queen) and the other being a subterranean chamber lying beneath the pyramid. The purpose of these two compartments is debatable. Scientists scanning the pyramid in 2017 discovered a massive vacuum above the grand gallery, which could hold one or more chambers.
THE HANGING GARDENS OF BABYLON, IRAQ

According to legend, the sixth-century B.C. Babylonian king Nebuchadnezzar II incorporated a massive maze of waterfalls and dense vegetation into his palace for his wife, Amytis of Media, who missed her lush homeland of Persia. Archaeologists are still debating whether the garden ever existed.
Several ancient writers described the gardens. “The entrance to the garden sloped like a hillside, and the various portions of the edifice rose from one another layer on tier, the aspect of the entire like that of a theatre,” said the first century B.C. Greek historian Diodorus Siculus.
Archaeological excavations at Babylon, which is located 60 miles (100 kilometers) south of Baghdad in modern-day Iraq, have not yielded a location that can be conclusively recognized as the Hanging Gardens. Furthermore, there are no extant Babylonian records that describe them. According to one opinion, Diodorus Siculus and other ancient historians got the site wrong, and the gardens were built at Nineveh, near modern-day Mosul in northern Iraq.
THE STATUE OF ZEUS AT OLYMPIA, GREECE

The sitting image of Greece’s principal Olympic deity was 40 feet tall when it was built around 450 B.C. (12 m). It was built primarily of ivory by the sculptor Phidias and “showed Zeus seated but almost touching the roof with his head, thus giving the impression that if Zeus arose and stood erect he would unroof the temple,” according to the ancient Greek writer Strabo, who lived from around 64 B.C. to A.D. 24.
Around A.D. 40, the Roman emperor Caligula attempted to steal it. Caligula ordered that the statue of Zeus, as well as other prominent god statues, be “brought from Greece, in order to remove their heads and replace his [Caligula’s] own in their place,” according to Suetonius, who lived between A.D. 69 and 122. Caligula, however, was slain before his commands could be carried out.
It is unclear when the statue was demolished. According to historical records, Christianity was the official religion of the Roman Empire in the fifth century A.D., and old Graeco-Roman faiths were being suppressed. It’s possible that it was destroyed during this time period.
THE TEMPLE OF ARTEMIS AT EPHESUS, TURKEY

The Temple of Artemis at Ephesus was built in 550 B.C. by Croesus, a Lydian ruler, and was acclaimed by ancient historians for its beauty. Previously, a smaller temple to Artemis, a goddess associated with animals and hunting, existed at Ephesus, but Croesus, who had recently conquered the area, greatly enlarged it, historian Michael Immendörfer wrote in his book “Ephesians and Artemis: The Cult of the Great Goddess of Ephesus as the Epistle’s Context” (Mohr Siebeck, 2017).
It was allegedly set on fire in 356 B.C. by a man named Herostratus who sought renown. It’s debatable whether Herostratus actually torched the temple, Immendörfer noted, noting that people might have been looking for a scapegoat since they didn’t want to think that a lightning bolt could have destroyed the goddess’s temple. In any case, the temple was reconstructed.
According to Immendörfer, the temple was devastated by an earthquake in A.D. 262 and robbed by the Goths – a group of Germanic people who most likely originated in Scandinavia. Whatever remained of the temple appears to have been abandoned or demolished about the fifth century A.D., as Christian sources describe the temple’s demise in this period.
THE MAUSOLEUM AT HALICARNASSUS, TURKEY

This tomb, built for Mausolus, a satrap of Caria in northern Anatolia who died in 353 B.C., left an indelible impression on ancient writers and gave rise to the term “mausoleum.” Pliny the Elder (A.D. 23–79) said that the building came about because a group of the best sculptors at the period — Scopas, Bryaxis, Timotheus, and Leochares — collaborated on the project despite the fact that they were rivals.
When Mausolus’ wife, Artemisia, died around 350 B.C., the mausoleum was still unfinished, and it was unclear whether the sculptors would be paid in the future. Despite this, the team persisted. “They did not, however, abandon their labor until it was finished, considering that it was both a legacy of their own reputation and of the sculptor’s art,” Pliny wrote.
Pliny described the structure as 140 feet (43 meters) tall, with a pyramid-shaped base and 63 columns at the top. The mausoleum’s remains can still be seen today, however, they are in ruins due to the passage of time and the reuse of stone for other buildings, which has progressively led the mausoleum to fall apart.
THE COLOSSUS OF RHODES, GREECE

The Colossus of Rhodes, a massive statue of the Greek sun god Helios, was built approximately 280 B.C. on Rhodes, an island off the coast of modern-day Turkey, and collapsed following an earthquake in 226 B.C. Nothing of the colossus exists now, and the actual location and height of the colossus are debatable among experts.
The statue itself was possibly 110 feet (34 meters) tall and stood atop a three-tiered column around 50 feet (15 meters) tall. Robert Kebric, a retired history professor at the University of Louisville, wrote in the Athens Journal of Humanities and Art in 2019. After analyzing descriptions by ancient writers, Kebric calculated that it would have a total height of 160 feet (49 m).
While some modern-day creative depictions have the monument straddling Rhodes’ bay, Kebric claimed that a more plausible placement was on the summit of the island’s capital city’s acropolis. Kebric reported that there were a number of temples and religious monuments in that location at the time.
THE LIGHTHOUSE OF ALEXANDRIA, GREECE

The lighthouse of Alexandria led ships into Alexandria, Egypt, one of the major ports in the ancient world, under the orders of Ptolemy II Philadelphus, who reigned from roughly 285 to 246 B.C. It was constructed on the island of Pharos, which is located at the entrance to Alexandria’s harbor. A causeway was built to connect the island to the mainland. The lighthouse featured a mirror that reflected the sun’s rays during the day, and a fire was lit at night and other times when it was essential.
The lighthouse’s height has been estimated to be roughly 400 feet (122 m). The lighthouse was in use throughout the Middle Ages, but it collapsed in the mid-14th century, according to Doris Behrens-Abouseif, a professor at the University of London’s School of Oriental and African Studies, in a 2006 paper published in the journal Muqarnas. Damage from earthquakes and coastal erosion contributed to its collapse, despite efforts to repair the damage throughout the Middle Ages.
What’s left of the lighthouse, as well as a major chunk of ancient Alexandria, are now submerged. Archaeologists uncovered the lighthouse’s remains in 1994, and they are still being studied.
Every country has to opt for an economic structure or model that defines how they generate money and revenue. Now, even though there are countries that follow socialism, communism, and many other apparatuses, it is important to keep in mind that most developed countries follow the capitalistic structure.
This is the reason why the corporate sector is growing at an expansive rate, where profits are made by creating needs within the society. In order to meet the growing demands of the people, organizations and industry owners invest in high-quality and advanced electric equipment so that an optimum level of productivity is achieved in a short span of time.
However, amid all this, the government, customers, and the corporate sector forget that all these instruments and equipment have a detrimental effect on the health of the planet. They release toxic carbon and greenhouse gas emissions that lead to global warming and climate change. In recent years, slowly, industry and organization owners are stepping up to understand their responsibility towards the planet and are investing in innovative corporate climate action plans.
Even though different sectors of society like agriculture, industrial, electrical, and healthcare are rapidly utilizing different technologies to speed up processes, they are being highly ignorant of the damage it is creating. The breakout of the global pandemic in March 2020 has given people and organizations plenty of time to think, introspect, and reflect on their actions and decisions.
This has also led to the acceleration of comprehensive corporate climate action plans that can bring significant changes in the environment. Below we have carefully curated a list of ideas, techniques, and plans that will work for the corporate sector:
Know More About Decarbonization Companies
It is not like companies don’t want to make efforts to bring in a change, most organizations are keen to contribute but do not know how to start. The process of lowering the overall carbon intensity in the environment is known as decarbonization. It is an idea that promotes that energy can be generated from alternate and non-replenishable sources like sunlight, water, and wind.
In addition, whether you own a small scale or a large scale business, a decarbonization company has a team of professionals who will guide you on how you can lower the carbon footprint of your industry via decarbonization techniques and equipment.
Say Yes to Energy Consultation
One of the few pros of climate change is that it has created several employment and business opportunities. Terms like global warming and sustainability are vast ideas that can come into effect only if people from all sectors put in collective efforts.
In order to do so, companies can approach an energy consultancy that will help them save the maximum amount of energy while making sufficient profits. This is one of the fastest-growing fields that can accelerate the impact of corporate climate action plans.
Renewable Energy Sources
This is one of the most common and most effective corporate action plans. Take some time out for research and invest in highly efficient renewable energy equipment like solar panels, hydropower, and windmills. They do not release any toxic carbon and greenhouse gas emissions, making the net-zero future a close reality.
Step Into the Future with a Component Service Provider
It is a good idea to join hands with a service provider as they will ensure that all the alternate energy instruments and equipment are installed in a precise and accurate manner. In addition, don’t forget to explore the websites of online electrical brands, they carry a vast portfolio of decarbonization equipment available at affordable prices.
Elon Musk doesn’t want to delay the space supremacy of human beings any further. The founder of SpaceX and Tesla has set a new schedule for getting to Mars.
Elon Musk, it turns out, believes he’d be “surprised” if humans didn’t land on “Mars within five years.” After being awarded Time Magazine’s Person of the Year for the year 2021, I spoke with them.
Elon Musk has big ambitions for a human colony on Mars, including a self-sustaining city based on solar-powered hydroponic fields that will house humans permanently. This is the first step toward Musk’s goal of permanently establishing a human presence on Mars.
Musk described the prospective Mars colony as “kind of like a modern Noah’s ark” in an interview with Time. But we’ll bring more than two – it’ll be strange if there are only two.”
Even said, Musk is known for releasing numerous estimations at the same time, and both SpaceX and Tesla are known for their delays. Musk admitted on an earnings call in 2020 that “punctuality is not my strong suit.”
Is it possible that we will be on Mars in five years? It’s not easy. Space policy analyst Greg Autry told Business Insider that SpaceX will not reach Mars until 2029, with or without NASA‘s cooperation.
Musk had previously stated that numerous astronauts would “likely perish” while traveling to Mars. To begin with, this has never been done before, so there is a lot that could go wrong. Furthermore, Musk has yet to unveil any clear Mars action plans. In February as also, Musk had declared in a Clubhouse conversation he wanted to deploy humans on Mars in approximately “five and a half years.”
Are Elon Musk’s projections realistic or just exaggerated, in your opinion?
