Mega-rich entrepreneurs are taking us where no human being has gone before.
- During the first golden era of space exploration, we went to the Moon. Then, says Dr. Michio Kaku, we sort of dropped the ball for 50 years.
- Space travel is very expensive, especially the way governments do space travel: It costs $10,000 to put a pound of anything into orbit around planet Earth.
- We need to have an infusion of public and private funds. That's where billionaires such as Elon Musk and Jeff Bezos come into the picture. With their help, we have new energies, new strategies and, most importantly, a new vision to go back into outer space.
Cook's commencement speech at Tulane University urges students to take action.
- Apple CEO Tim Cook gave a commencement speech at Tulane University on May 18th.
- Cook cautioned the graduates to not get caught up in echo chambers and algorithms.
- He acknowledged the failures of his generation.
New computing theory allows artificial intelligences to store memories.
- To become autonomous, robots need to perceive the world around them and move at the same time.
- Researchers create a theory of hyperdimensional computing to help store robot movement in high-dimensional vectors.
- This improvement in perception will allow artificial intelligences to create memories.
Don't start investing in flux capacitors just yet, though.
- The second law of thermodynamics states that order always moves to disorder, which we experience as an arrow of time.
- Scientists used a quantum computer to show that time travel is theoretically possible by reverting a simulated particle from an entropic to a more orderly state.
- While Einstein's general theory of relativity permits time travel, the means to achieve it remain improbable in nature.
Dementia, disrespect, and loneliness – that is not your future, says aging expert Ashton Applewhite.
- The best anti-aging advice? Stop stereotyping old people! Cultural messaging about the pitfalls of old age causes undue stress that prematurely ages the brain and shortens life spans.
- People who have a positive outlook on aging can live 7.5 years longer than those who buy into cultural stereotypes about getting old.
- It's important to look at the positives of aging, not just the risk factors: Alzheimer's rates are declining, 'mental sifting' can make us wiser, and older workers injure themselves less often than younger workers.
