Bill Nye on Gravitational Waves: There's Nothing "Basic" About Basic Research
Bill Nye is always dressed for a party, but this time his celestial bow-tie pays respect to one of our era's greatest discoveries: gravitational waves.
Bill Nye, scientist, engineer, comedian, author, and inventor, is a man with a mission: to help foster a scientifically literate society, to help people everywhere understand and appreciate the science that makes our world work. Making science entertaining and accessible is something Bill has been doing most of his life.
In Seattle Nye began to combine his love of science with his flair for comedy, when he won the Steve Martin look-alike contest and developed dual careers as an engineer by day and a stand-up comic by night. Nye then quit his day engineering day job and made the transition to a night job as a comedy writer and performer on Seattle’s home-grown ensemble comedy show “Almost Live.” This is where “Bill Nye the Science Guy®” was born. The show appeared before Saturday Night Live and later on Comedy Central, originating at KING-TV, Seattle’s NBC affiliate.
While working on the Science Guy show, Nye won seven national Emmy Awards for writing, performing, and producing. The show won 18 Emmys in five years. In between creating the shows, he wrote five children’s books about science, including his latest title, “Bill Nye’s Great Big Book of Tiny Germs.”
Nye is the host of three currently-running television series. “The 100 Greatest Discoveries” airs on the Science Channel. “The Eyes of Nye” airs on PBS stations across the country.
Bill’s latest project is hosting a show on Planet Green called “Stuff Happens.” It’s about environmentally responsible choices that consumers can make as they go about their day and their shopping. Also, you’ll see Nye in his good-natured rivalry with his neighbor Ed Begley. They compete to see who can save the most energy and produce the smallest carbon footprint. Nye has 4,000 watts of solar power and a solar-boosted hot water system. There’s also the low water use garden and underground watering system. It’s fun for him; he’s an engineer with an energy conservation hobby.
Nye is currently the Executive Director of The Planetary Society, the world’s largest space interest organization.
Bill Nye: The announcement was made that we detected a gravity wave from a distant object that had a very big or catastrophic gravity event millions of years ago when the gravity wave showed up here. Gravity wave, obviously how hard could it be? So when I do experiments on light to detect particles we detect particles of light. When we do experiments on light to detect waves we detect waves of light. When we look at forces, that's the transmission or the force over a distance is the transmission of energy, so we can find energy traveling in waves, we can find energy traveling in packet or particles. So people have speculated since – well, this is the hundredth anniversary of Einstein publishing his landmark papers, people have speculated on the nature of gravity. Now understand we understand gravity with extraordinary precision. We land spacecraft on Mars precisely.
Everybody watching this has probably used a global positioning system on his or her phone or in a car or in an airplane that's navigating with global positioning. Those satellites that enable the system to work rely on both special relativity, which is the influence of the speed of the spacecraft relative to the airplane or ground, and general relativity, which is the speed of time as effected by the Earth's gravity. So people have suspected or speculated that there will be waves of gravity. And ways of gravity would date back to the big bang, to the origin of the universe 13.7 billion years ago, but they're very weak, extraordinarily weak. Compare how easy it is to use chemical energy to hold a ball up against the pull of gravity or just hold yourself upright against the pull of gravity. Gravity, of the forces of nature, is the weakest one and so if its energy or force or influence moves at the speed of light, like everything else does, does it move in waves?
Well to detect them you'd need an extraordinarily sensitive instrument, crazy sensitive because this influence is so weak. And we did it. We set up an instrument in Louisiana and in Washington state using these mirrors and as the gravity wave passed through the earth the mirrors moved, and with extraordinarily sensitive measurement of the waves of reflected laser light we were able to detect this small movement, these small movements. And so what does that mean for us? Well, I don't know. But the discovery of relativity lead to global positioning systems and the Internet and our ability to plant crops with precision and feed 7.3 billion people where we used to only feed 1.5 billion people. So who knows where this discovery will lead. But I wouldn't be surprised if it leads to a new understanding of another aspect of physics and a new source of energy or we prove to ourselves that there is no other source of energy and we got to rely on wind or solar or what have you. Who knows what it will need to. But the basic research is worth celebrating. This is a society that uses its intellect and treasure to make discoveries about nature and ultimately where we all fit in in the cosmos, our place in space. So if you're a human able to hear this broadcast or watch this broadcast, celebrate it. Humans have made another discovery about the universe. It's not bad.
At 4am on September 14, 2015, a team of over 1,000 scientists who form the Laser Interferometer Gravitational-Wave Observatory (LIGO) confirmed an aspect of Albert Einstein's general theory of relativity.
They monitored an energy vibration just four one-thousandths of a diameter of a proton, and it set the world ablaze with celebration. Well, more than a year later, Bill Nye is still celebrating. He never stopped. These kinds of events are rare and epochal – scientists have been looking for proof of this since 1916, when Einstein published his landmark papers.
What the observation of the gravitational wave confirmed is that space and time are really one unit — space-time — that exist as part of a gravitational grid. When that grid is disturbed by massive events in space, the space-time continuum itself is altered. In this case, the event was truly epic: two black holes (one 36 times as massive as the Sun, the other 29 times) collided almost at the speed of light and formed a single black hole, during which they released 50 times the amount of energy released by all the stars in the known universe at that same moment. We’re still feeling the effects of it at a quantum level, and in many ways the ripple is only set to amplify in terms of the discoveries and technology this insight will lead to, eventually changing our daily existence in a very tangible way.
Considering that Einstein’s discovery of relativity led to things like GPS, the internet, and precision agriculture, we can only imagine what existence-altering innovations the proof of gravitational waves will bring down the line. Nye expects that it will lead "to a new understanding of another aspect of physics" and insight into energy sources that will steer us down one course of energy production.
Bill Nye's most recent book is Unstoppable: Harnessing Science to Change the World.
Innovation in manufacturing has crawled since the 1950s. That's about to speed up.
SEAL training is the ultimate test of both mental and physical strength.
- The fact that U.S. Navy SEALs endure very rigorous training before entering the field is common knowledge, but just what happens at those facilities is less often discussed. In this video, former SEALs Brent Gleeson, David Goggins, and Eric Greitens (as well as authors Jesse Itzler and Jamie Wheal) talk about how the 18-month program is designed to build elite, disciplined operatives with immense mental toughness and resilience.
- Wheal dives into the cutting-edge technology and science that the navy uses to prepare these individuals. Itzler shares his experience meeting and briefly living with Goggins (who was also an Army Ranger) and the things he learned about pushing past perceived limits.
- Goggins dives into why you should leave your comfort zone, introduces the 40 percent rule, and explains why the biggest battle we all face is the one in our own minds. "Usually whatever's in front of you isn't as big as you make it out to be," says the SEAL turned motivational speaker. "We start to make these very small things enormous because we allow our minds to take control and go away from us. We have to regain control of our mind."
Is focusing solely on body mass index the best way for doctor to frame obesity?
- New guidelines published in the Canadian Medical Association Journal argue that obesity should be defined as a condition that involves high body mass index along with a corresponding physical or mental health condition.
- The guidelines note that classifying obesity by body mass index alone may lead to fat shaming or non-optimal treatments.
- The guidelines offer five steps for reframing the way doctors treat obesity.
A new 5-step system for treating obesity<p>To help primary care practitioners better treat obesity, the doctors outlined five steps:</p><ol><li>Recognition of obesity as a chronic disease by health care providers, who should ask the patient permission to offer advice and help treat this disease in an unbiased manner.</li><li>Assessment of an individual living with obesity, using appropriate measurements, and identifying the root causes, complications and barriers to obesity treatment.</li><li>Discussion of the core treatment options (medical nutrition therapy and physical activity) and adjunctive therapies that may be required, including psychological, pharmacologic and surgical interventions.</li><li>Agreement with the person living with obesity regarding goals of therapy, focusing mainly on the value that the person derives from health-based interventions.</li><li>Engagement by health care providers with the person with obesity in continued follow-up and reassessments, and encouragement of advocacy to improve care for this chronic disease.</li></ol><p>Insider noted that some health professionals and body-positive advocates don't think the guidelines go far enough in reframing obesity treatment.

Berry</a> argued that misplaced "medical and political correctness" may lead to the abrogation of the physician's responsibility to properly care for patients.</p><p style="margin-left: 20px;">"For example, some doctors are now even reluctant to raise the issue of obesity lest they be accused of fat shaming by not accepting their patients' proportions (despite the quote at the head of this opinion piece), and thereby receive poor approval ratings in an atmosphere where popularity is equated with good healthcare."</p><p>Berry offers a list of nine steps that he thinks could help the healthcare industry better treat obesity, without shaming patients or falling prey to political correctness.</p>
Here's why you might eat greenhouse gases in the future.
- The company's protein powder, "Solein," is similar in form and taste to wheat flour.
- Based on a concept developed by NASA, the product has wide potential as a carbon-neutral source of protein.
- The man-made "meat" industry just got even more interesting.
