Quantum advantage is the milestone the field of quantum computing is fervently working toward, where a quantum computer can solve problems that are beyond the reach of the most powerful non-quantum, or classical, computers.Quantum refers to the scale of atoms and molecules where the laws of physics as we experience them break down and a different, counterintuitive set of laws apply. Quantum computers take advantage of these strange behaviors to solve problems.There are some types of problems tha ...read more
There isn't a corner of the globe where you can't find people living. Even in some of the most extreme environments on the planet, people manage to get by, largely thanks to the innovations of technology. It's easy to take these technological innovations — which have facilitated our dispersal throughout the world — for granted. In fact, common items like baskets, bags, pottery, and woven string were once considered innovative, even though they might seem humble compared to the technologies b ...read more
You may have seen it happen in the movies, or on TV: an astronaut swims their way through space to get from point A to point B. It may look a little fun, but unfortunately, humans can’t swim through space because there’s not enough stuff to swim through.What Is the Physics of Swimming?We can easily swim through water because water is dense enough to allow us to push back on it with our hands and get something for our effort. By conservation of momentum, when we push on the water, the water p ...read more
The last few years have brought a new autumn ritual. Starting in September, drug stores and supermarkets run promotions for flu shots and COVID-19 vaccines. Customers who get jabbed at the in-store pharmacy earn a $10 off coupon or maybe a gift card. Both vaccines can be given at once, and for some people, a Respiratory Syncytial Virus (RSV) vaccine might also be recommended.Is this the new vaccine normal for COVID-19? An annual shot along with others to protect against seasonal viruses?Some epi ...read more
Along the Equator in the eastern Pacific Ocean, the El Niño climate phenomenon has been coming on strong in recent weeks. You can see that strength in the image above, which shows how temperatures at the ocean surface vary from normal right now. El Niño's fingerprint is seen in that broad yellow, orange and red swath along the Equator, indicative of abnormally warm water. We're Now in Strong El Niño Territory"El Niño is currently chugging along, and forecasters expect it to continue for th ...read more
