If the moon were only 1 pixel on your screen, how big would the rest of the solar system be?
Just click this link, I beg you, and prepare to have your mind blown.
Absolutely amazing. Fantastic work by designer Josh Worth.
For a a different look at the problem of cosmic distance, check out my video “How Big is the Solar System?”:
And for lots more fun ways to look at the scale of the universe maybe watch this one called (naturally) "The Scale of the Universe":
All too familiar with all the things he had done or not done in his life, novelist Keiichiro Hirano had trouble accepting himself as a “good” or a “bad” person, until he realized that maybe he was a bit more complicated than that.
The Golden Ratio is Everywhere.
Do you think parents should be able to select their children’s talents and personalities, or do you want to run and hide in the woods at the thought of it? Whatever your opinion, philosopher Julian Savulescu wants you to take the question seriously.
Julian is the director of The Oxford Centre for Neuroethics at Oxford University and his TEDxBarcelona talk — "Pills that improve morality" — proposes the fascinating idea that humans may have a moral imperative to use advancements in biology and psychology to augment and improve human morality.
An interesting topic indeed, and worth the read.
In the late 1800s and early 1900s, logging railroads stretched deep into the heart of the White Mountains of New Hampshire. Long gone now, nature now reclaims what was once hers, yet the influence of the logging railroads can still be seen.
aldelie penguins spend their (austral) winters in the seas surrounding the antarctic pack ice - about 4,000km from their southern spring breeding grounds - where they fatten on krill. the krill feed on phytoplankton beneath the icebergs, but warming waters due to climate change has reduced their numbers by up to 80 percent as the plankton, which are now unable to access cold water nutrients, are dying off.
adelies are the most southern living penguin, but head north as the summer ends to escape the protracted darkness of the winter. a warming climate, however, has meant a reduced northern icepack, and has seen the encroachment of other penguins onto their southern summer territory who previously found it too cold. the adelie population northeast of the ross sea, for example, has declined by 90 percent.
as one adelie expert put it, these penguins face possible extinction not merely by a loss of habitat, but by an unshakable fear of darkness; adelies need light, if only twilight, to forage and navigate, and as comfort against predators. but as they are pushed further south they may ultimately find themselves trapped behind a curtain of polar night for which they have no hardwired strategy.
