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.
If you were to trace both “sides” of a Möbius strip, you would never have to lift your finger. The figurative and narrative implications of the Möbius strip are rich: when you try to go forward, you ring sideways, when you try to circle in, you find yourself outside. The continuum of crossing a Möbius strip is emblematic of how we experience time in a nonlinear way. ‘Time passes.’ ‘That’s how it goes,’ Aureliano admitted, ‘but not so much.’”The unorientable quality of the Möbius strip is perhaps its most distinctive. The Möbius band is used in hardware and popular imagery, but the mathematical and scientific fascination with the Möbius strip has also endured for over a century.
People “should not really consider themselves protected until after a week or two following dose two,” he adds. The researchers now are studying whether outcomes vary for people on specific types of these drugs, the release states. Experts call this a One Health approach or concept, and they want governments to factor it into policies, Robbins reports. As humans move into more of Earth’s natural environments, more spillovers of animal diseases into humans are expected. “The spillover of animal, or zoonotic, viruses into humans causes some 75% of emerging infectious diseases,” Robbins writes.
The graph also helped make the researcher a target of attacks by climate change deniers. They have merely changed their tactics, Mann contends in his book The New Climate War: The Fight to Take Back Our Planet. You argue that the climate change deniers are going extinct and being replaced by a new group that you call “the inactivists.” Who are the inactivists? They are trying to convince people that climate change is not the result of their corporate policies but of our own individual actions. Can you give some concrete examples of how the fossil fuel industry has been working to create divisions within the environmental community?
Think of it this way: for every cheetah on the planet, there are more than four Starbucks coffee shops. Even though these communication hubs only comprise around 10 percent of the landscape, cheetahs spend most—sometimes all—of their time within them. “This is basically a long-term tradition, which is passed on from cheetah generation to cheetah generation. “I told him, ‘Look, Wilfred, I have the idea that they are actually there because of these marking trees. In all, the number of calves lost to cheetah predation fell by a whopping 86 percent.
The pandemic has transformed lives and livelihoods. He says a lot of the words that came up fresh to many people in 2020 had existed in scholarly literature for decades. “So, for example, ‘contact tracing’ is attested from 1910—been in use for well over a century. But it took on new life during the pandemic. At a recent virtual meeting, they voted on the 2020 Word of the Year.

\" \" A mule-drawn wagon carrying the casket of Dr. Martin Luther King Jr., is followed by dignitaries and thousands of people as it moves en route to Morehouse College, Atlanta for his memorial service on April 9, 1968. \"The same criticisms made against Colin Kaepernick and the Black Lives Matter movement today were trotted out against Martin Luther King and Rosa Parks 60 years ago. But Clayborne Carson, history professor at Stanford University and founding director of The Martin Luther King, Jr. Research and Education Institute, points out that King didn't retire after the passage of the Voting Rights Act. Of course, Americans have every reason to venerate Martin Luther King and to celebrate his accomplishments.

\" \" Composer Leonard Bernstein used a performance the night before Richard Nixon's inauguration as an \"anti-inaugural.\" On January 20, 1973, the second presidential inauguration of Richard Nixon — elected in a landslide victory — took place amidst shaking signs and shouting protestors. But at the exact same time a free and unofficial inauguration concert at the National Cathedral took place thanks to legendary conductor Leonard Bernstein. For even more on the animosity between Leonard Bernstein and Richard Nixon, we'd recommend a deep dive into \"The Bernstein Files,\" a three-part multimedia series in The New Yorker from classical music expert Alex Ross. Now That's Interesting When the Philadelphia Orchestra was asked to perform President Richard Nixon's 1973 inauguration concert, 16 members requested the night off.
The Secret Service has, during the four years of Trump's tenure, spent enormous amounts of money providing protection to Trump's children. The adult Trump children have caught plenty of flak during their father's administration for hauling their Secret Service details all over the world at the U.S. taxpayer's expense. While in office, neither the president nor the vice president can decline Secret Service protection, but their spouses and adult children can. Almost all presidential families have accepted full Secret Service protection for as long as the law allows. Despite the cost, the Trump family is doing nothing unusual by accepting Secret Service protection at home and while traveling abroad.
\" \" Cake flour has less protein than all-purpose flour, which means you end up with a lighter and moister end product. Now that the world is on a mission to bake as much in the kitchen as humanly possible, ingredients like all-purpose flour and cake flour are in the spotlight. For the amateur bakers out there who can't discern flour from baking soda or sugar from salt, here's an easy explainer that tells you everything you need to know about the difference between cake flour and all-purpose flour. Your typical batch of cake flour contains around 5 to 8 percent of protein, compared to all-purpose flour, which has around 10 to 13 percent. And consider spending a little extra to buy high-quality cake flour, especially for use in simple cake recipes where flavor is critical.
Images are visceral reminders of the pandemic’s dangers, revealing unsettling events behind closed doors, showing us suffering’s human face. Is there evidence showing that shocking images reliably persuade? In our study, we found that participants also believed shocking images would deliver a persuasive punch, moving people’s attitudes about the risks of the coronavirus. Viewing disturbing images, we use the sadness or outrage we ourselves feel as a guide to understand how others will feel. If you entered our study doubting the threat, the images didn’t shock you and, accordingly, didn’t move your thinking.
Downing Street said Mr Johnson was the first European leader to receive a call from the President since his inauguration in Washington last Wednesday. The phone cable should be visible in the mirror descending from Boris Johnson’s watch, in this official Downing St picture. The Prime Minister is regarded with deep suspicion by some senior Democrats around Mr Biden who - unlike the former president - was no fan of Brexit. \"We're in no doubt of the importance that President Biden places on the UK and US relationship and the Prime Minister looks forward to having a close relationship with him.\" Washington insider issues Joe Biden trade deal warning[SPOTLIGHT]Boris Johnson tweeted: 'Great to speak to Joe Biden'
This is unfortunate because a weak get out the vote effort is probably worth a couple of points on election day. It is unfortunate because some Trump scandals increase, rather than decrease, his numbers. He could suddenly gain a couple of points if he says or does just the wright/wrong things. Then Wikileaks, weak as it is, or some other issue, will come into play and knock two points off of her numbers. It is unfortunate because the difference between Clinton and Trump is now between about 5 and 7 points, and 2 + 2 + 2 = 6.
I’m venting now because I’ve discovered a phrase that elegantly captures my peeve: wishful worries. How can we protect privacy in an age of tech-enabled telepathy?”We expect boosters of techno-enhancement to minimize technical obstacles. Brain chips could, in principle, give us enormous power over our brains, hence minds, hence behavior. He and others also warned that tyrants might use brain chips to monitor and control our thoughts. In 2003 the U.S. Council on Bioethics, a group convened by President George Bush, brooded over brain chips’ possible effects on STEM education.
-Henry Wadsworth LongfellowOnce a year, in mid-August, the Perseid Meteor Shower comes to town. If you're going to see just one meteor shower a year, make it this one. Because the Perseid Meteor Shower is in town! These \"shooting stars\" are what meteors are, and the Earth passing through these dusty trails are when meteor showers occur. That's where meteor showers come from; now get out there and enjoy it!
Apple’s Siri, Google Assistant, and Amazon’s Alexa collectively service zero African languages. For them, speech recognition technology could help bridge the gap between illiteracy and access to valuable information and services from agricultural information to medical care. Languages spoken by smaller populations are often casualties of commercial prioritization. Instead of exploiting data sets from unrelated, high-resource languages, we leveraged speech data that are abundantly available, even in low-resource languages: radio broadcasting archives. The second, West African Virtual Assistant Speech Recognition Corpus, consists of 10,000 labeled audio clips in four languages.
Perry is also an educator who has taught and developed curriculum on African American history to high school students. The practice led to the inequality of wealth between Black and white people that continues to this day. She's the African American woman we can thank for inventing the sanitary belt in 1957 and revolutionizing women's lives across the entire globe. When Kenner invented her modern-day maxi-pad, it was illegal for African American women to apply for patents. But African American Mose Norman, who was a prominent landowner, chose to exercise his democratic right anyway.
Cheers to a New Year and another chance for us to get it right. What I've learned amazes and enthralls me, and gives me a tremendous joy whenever I lose myself thinking about it. If you can find the big dipper in the sky, you'll know where to look for meteors. It's the greatest story ever told, only it's a story that only a few people in the world ever really learn well. So here's to starting 2010 with a bang, and to you, my wonderful readers, for helping inspire me to keep doing what I love!
Peer-reviewed claims of a small planet around Alpha Centauri B in 2012 evaporated a few years later, found to be products of stellar noise.) “If it’s in the habitable zone around Alpha Centauri A, that’s an Earthlike orbit, so observing six months later would probably have nailed it,” Fischer says. “Without that, this isn’t a planet detection paper, it’s a demonstration of NEAR’s capability to monitor Alpha Centauri in the mid-infrared. “Because Alpha Centauri A is a twin of our own sun and less than five light-years away, it really is our closest solar neighbor,” Beichman says. Some of these could image and search for signs of life on small rocky planets around Alpha Centauri as well as many other nearby stars.
