By 2050, the UN estimates that as many as 3.2 million people will live to 100 compared to 316,000 in 2011. Also, a 2013 study from the University of Massachusetts found that 25 year olds today can look forward to "2.4 more years of a healthy life" while a 65-year-old today can expect to live 1.7 extra years - than people who lived 20 years ago.
See if you can answer this fish riddle. Imagine you’re a cargo driver who has agreed to transport several tanks of a critically endangered fish species to a new aquarium. Unfortunately, as you’re passing through shark-infested waters, the boat is battered by a fierce storm, tossing your cargo overboard. There’s one rescue sub at your disposal, but you only have enough fuel for one trip to the ocean floor. Before deciding to rescue them, you need to know where the tanks are so you can gather them all in one quick pass. Not a single fish can be lost.
Everything in this world is based on one algorithm. Theoretical physicist Geoffrey West talks about just how connected every living organism on earth is by way of energy and resources being supplied to cells — and by a methodology known as "quarter scaling."
There were many great scientists whose achievements were undervalued during their lifetimes, or who are nearly forgotten and often totally overlooked today. Here, Hank Green talks about five of those scientists – (Alfred Wegener, Rosalind Franklin, James Clerk Maxwell, Henrietta Swan Leavitt and Ada Lovelace) - who didn’t get the sort of appreciation they deserved in the episode of SciShow's “Great Minds Compilation” series.
Our Universe is expanding. No matter what galaxy you’re in, all the other galaxies are moving away from you. Well, if you’re curious, point your telescope far enough away; you’ll find that everywhere in the universe is moving away from everywhere else.
The Fédération Aéronautique Internationale has demarcated the Karman Line - which lies at an altitude of 100 kilometers (330,000 feet; 62 miles) above the Earth's sea level - as the boundary where space begins. But, NASA spokesperson Dan Huot explains from a physical science’s perspective that “there is no hard-definable point where space begins; the atmosphere just gradually decreases the higher you get.”
With the discovery of things like Relativity and Quantum Mechanics, it might sometimes feel like there are just a few small problems left for physicists to solve. Well, here are 5 mysteries about the universe that still continue to baffle physicists and render their attempts unavailing to this day.
As many as 300 million people around the world suffer from asthma, and around 250,000 die from it each year. Also, with its rates surging around the globe over the past few decades, there is currently no cure for asthma.
All lives on earth are constantly evolving. And as one of the living beings, humans too are evolving. In the last 130 years, humans have already seen a boom in height. So even 100 years from, we will be getting much taller.
