It's not the apple bit that I have a problem with; that's an important part of the story, and even historically accurate! In a flash of insight, he realizes that there must be some force pulling the apple toward the earth. The man himself is recorded as saying that his \"eureka\" moment really did come after seeing an apple fall from a tree.
Using science and art together not only energized my studio practice, but it also changed the way I see our universe. I want to figure out a way to have the least amount of distance between the viewer and the art. I want to figure out a way to have the least amount of distance between the viewer and the art. My goal is to lure in science phobic people with handsome art, then blow their minds with cool science.

The reason Christmas trees topple so easily is because their base is so small. Anything making small contact with the ground relative to its size is going to be fairly unstable. It only has to be pushed past its edge of contact with the ground before it starts to tip over. Likewise, an object will tip over more slowly when it's center of mass is further away from the pivot point. That means the menorah, with the higher center of mass, will be easiest to control and easiest to juggle.
What's more, both are widely known to donate hundreds of millions of dollars to the American Kidney Fund, covering the vast majority of the nonprofit’s budget. The social worker paused, then asked if she’d heard about the American Kidney Fund. They found fewer kidney transplants, higher rates of hospitalization, and lower rates of overall survival among dialysis patients at for-profit clinics. Records from the California Secretary of State showed that dialysis corporations forked over upwards of $110 million via the California Dialysis Council in 2018. Unlike Karabasz, who blames AB 290 and those behind it for the uncertainty of her position, Carroll says some responsibility falls on the American Kidney Fund.
Wellesley College biologist Heather Mattila went to Vietnam to understand how Asian honeybees defend themselves from the hornets there. “Giant hornets will hunt honeybees on their own and grab them one by one. The alternative to covering their house in ...[CLIP: Censored beep sound]... was annihilation of the colony in the face of overwhelming giant hornet invasion. Asian honeybees are a different species than the Western honeybees in Europe and North America. I didn’t have a lot of personal experience with Asian bees, and so meeting them was kind of like meeting the crazy cousin of the bees you know really well.
3-D printing of human corneas may end wait times for people on transplant waiting lists. 3-D printing is a manufacturing process that creates a physical object from a digital design. Now, according to a paper published online on May 30, 2018 in the journal Experimental Eye Research, scientists are using 3-D printers to make human corneas — an advancement that could dramatically ease the shortage of corneas from donors. However, this promising 3-D printing technique may help people see better without the prolonged wait. That's where this new 3-D printing technique comes into play.
If you can find the dead animal yourself, carefully remove it using gloves. Donning gloves again, scrub down all surfaces that had any contact with the dead creature with a commercial disinfectant or diluted bleach solution and let the car air out as much as possible. While Simmons says that dead animal calls are \"pretty rare,\" he's seen cases where rodents have climbed into the air conditioner's evaporator unit and gotten trapped, spreading the stench throughout the whole vehicle. You could try to sell it, but who's going to buy a car that wreaks of dead opossum? Not only could the dead animal result in physical damage to the engine, but its decomposing fumes might count as a biohazard.
Editor’s Note: This blog was originally posted in December 2008 to commemorate the 40th anniversary of Apollo 8’s historic mission. On December 21, 1968, Apollo 8 was launched on one of the greatest journeys in the history of human exploration. Not only was the clock ticking, but also the CIA had informed the agency that it believed the Soviet Union was on the verge of launching cosmonauts on a moon mission. In August 1968 NASA's Apollo Spacecraft Program Office manager, George Low, proposed making Apollo 8 a mission to circumnavigate the moon some 234,000 miles away.

Spencer Platt/ Getty ImagesThe best thing to do during a snowstorm is to stay indoors. But if you absolutely need to get somewhere on foot, you'll have to be very smart in order to survive. Loose, warm, layered clothing is the way to go. Loose clothing helps the blood flow, increasing warmth. Snowstorm conditions are usually accompanied by limited visibility, so make your outer layer a bright color so you can be seen by others.
You also must fill out a money order correctly, otherwise it will have to be canceled and refunded, and then repurchased. AdvertisementAdvertisementBefore you go to buy a money order, make sure you know what types of payment are accepted. The amount will be printed when the money order is prepared by the issuer, but you'll fill in everything else. Fill in the recipient's address and your address, if required, depending on the type of money order. Sign the money order in a \"Signature\" or \"Purchaser\" field, if one is required.
On December 14, 2020, a camera onboard a satellite recorded something that looked like a brown blob streaking across South America. Individuals on the ground witnessed something more striking: a total solar eclipse, or a daytime blackout triggered by the moon blocking the sun and throwing its shadow on Earth. Though total solar eclipses happen relatively frequently—about once every 18 months—seeing them is lucky. In about 600 million years, total eclipses will stop. The temporary nature of these alignments makes all their recordings valuable, even when the perspective makes what feels like a boundary-breaking moment—shocking darkness in the middle of the day—seem small.
This is called Chronic Kidney Disease and it’s a growing global problem. Unless a donor kidney can be found for a transplant - patients with kidney failure require dialysis. Dialysis does not cure kidney disease and in the case of end stage kidney failure—a patient must remain on dialysis until a new kidney can be found. And yet, studies show that despite having higher rates of kidney disease, racial and ethnic minorities often struggle to afford dialysis. But for those with chronic kidney disease, there is really only one option: stay in the system, stay on dialysis, wait for a kidney—or die.
\" \" Galactic civilizations looking to postpone the end of the universe may be wise to stock up on a few stars like our sun. But it's also possible that you, gentle reader, are an immortal member of a galactic civilization in a distant future. If you're the former, then have a listen to the recent Stuff to Blow Your Mind podcast episode \"Galactic Civilization's End.\" In 2018, astrophysicist Dan Hooper pondered the question of a galactic civilization's long-term survival and contended that annihilation might at least be postponed with a little hoarding. If star-jacking isn't your style, physicist Alan Guth – who, by the way, developed cosmic inflation theory – told the BBC that a galactic civilization might be capable of creating its own pocket universe.
Richard Atrero de Guzman/Anadolu Agency/Getty ImagesIn a long-awaited ruling, the U.S. Department of Transportation (DOT) announced on Dec. 2, 2020, that \"carriers are not required to recognize emotional support animals as service animals and may treat them as pets.\" This ruling came after a skyrocketing number of pets flying as service and \"emotional support animals\" (ESAs) — up 150 percent between 2015 and 2017, according to Delta — had prompted the airline and others to enact more stringent requirements for on-board animals. \"The research on the positive impact that emotional support animals have on people who are struggling with mental illness is pretty plentiful,\" says psychologist Tanisha Ranger, who works mainly with veterans. Many passengers looking to avoid this fee had started to classify their pets as emotional support animals. And when untrained animals attack innocent bystanders, it further creates stigma for those who actually need service animals.\"
When bin Laden became a wanted man, running from the U.S. government, he began wearing a black cowboy hat when out in public, thinking it would shield his identity from spy satellites and drones. Bin Laden was an intense and religious person, joining the zealous Muslim Brotherhood in high school. Initially, bin Laden denied involvement, but in October 2004, he released a video claiming responsibility and decrying American intervention in the Middle East. But it was the final release on Nov. 1, 2017 that featured what seemed like a treasure trove of data, including 79,000 audio and image files, plus al-Qaida \"home videos.\" But what seems to pique everyone's curiosity is bin Laden's obsession with hentai — anime porn.
Muslim terrorist group al-Qaida claimed responsibility for the attacks. But almost immediately, conspiracy theories started flying around. Some theorists believed that the U.S. government had advance warning of the attacks, but let them happen anyway. Others claimed that the government actually engineered the attacks, and that al-Qaida wasn't even involved. There was also a lack of booming sounds and flashes of light characteristic of explosions [source: Thomas].
“We're also being exposed to many more PFASs via the drinking water,” Wang says. Higgins notes that people are also exposed to the compounds in substances besides drinking water, such as household products and food. “Aggressively addressing PFAS in drinking water continues to be an active and ongoing priority for the EPA,” an EPA spokesperson wrote to Scientific American. “The agency has taken significant steps to monitor for PFAS in drinking water and is following the process provided under the Safe Drinking Water Act to address these chemicals.”Technologies to remove PFASs from drinking water exist on both household and municipal levels. Some states have instituted or proposed limits on PFASs in drinking water, but experts say federal action is needed to tackle such a widespread problem.
Though small, ants are mighty; individual ants can withstand more than 5,000 times their own weight by some estimates. “Ants are like no living thing on Earth,”In addition to their strength, speed, and raft-crafting abilities, ants are also excellent atFlocking physics Researchers at the Georgia Institute of Technology have studied the unique collective behavior that arises when fire ants band together. Physics offers a few hints.Flocking (like raft-forming) is an example of active matter: systems whose constituent elements consume energy. Active matter is still a relatively new classification of soft matter; one of the most well-known mathematical models describing active matter — the Vicsek model — was published in 1995. Collective behavior arises as a property of groups but is not necessarily shared by the individual participants themselves.
Altogether, the planet lost a whopping 28 trillion tons of ice between 1994 and 2017. It accounts for both the Greenland and Antarctic ice sheets, Arctic and Antarctic sea ice and mountain glaciers all over the world. Since the 1990s, Antarctica has lost more than 2.6 trillion tons and Greenland has lost nearly 4 trillion. These ice shelves help to stabilize the ice sheet’s marine-terminating glaciers and hold back the flow of ice behind them. In addition to the ice sheet’s losses, Antarctica’s ice shelves have lost more than 8.6 trillion tons of mass since the 1990s.
But for more than a decade he has also courted a more contentious subject—namely, space aliens, including how to find them. Scientific American spoke with Loeb about the book, his controversial hypothesis and why he believes science is in crisis. And most importantly, I don’t need to think about what’s wrong with all the things that other people say! Speaking of important things, here is one I think we both agree on: in science, we must keep each other honest. I don’t see the search for technological signatures any differently from the search for the nature of dark matter.
