There IS Actually A Reason Why Seconds And Minutes (and Degrees For Geometry) Are In Base 60 Instead

the fact elon mask genuinely might ruin the night sky for everyone makes me wanna sharpen my shovel and get to work

human brain: Opportunity rover accomplished its mission and then some! It lasted far longer than we could’ve ever hoped. This should be celebrated, Opportunity did really well.

monkey brain: BUT SHE DIED ALL ALONE AND IN THE DARK AND ON A PLANET ALL THE WAY OUT IN SPACE AWAY FROM HOME!!! DOES SHE KNOW HOW PROUD OF HER WE ARE?! DID SHE THINK WE FORGOT ABOUT HER?! I LOVE HER AND I WANT HER TO BE HAPPY AND TO THRIVE AND I JUST WANT TO HUG HER AND LET HER KNOW HOW MUCH I CARE ABOUT HER!!! WE DIDN’T FORGET ABOUT YOU, OPPY!!! WE LOVE YOU SO MUCH AND I WOULD KILL ANYONE AND EVERYONE JUST FOR YOU TO HAVE PASSED AMONG FRIENDS AND FAMILY HERE ON EARTH!!!

the new composite james webb image is so beautiful ive been staring at it for 10 minutes straight

featuring jupiters rings, amalthea (along with a bunch of other moons), the northern and southern auroras, and the great red spot

VIDEO FROM THE SURFACE OF A COMET

This is truly incredible.

Details:

Remember Rosetta? That comet-chasing European Space Agency (ESA) probe that deployed (and accidentally bounced) its lander Philae on the surface of Comet 67P? This GIF is made up of images Rosetta beamed back to Earth, which have been freely available online for a while. But it took Twitter user landru79 processing and assembling them into this short, looped clip to reveal the drama they contained.

Quantum tunnelling

Tunneling is a quantum mechanical effect. A tunneling current occurs when electrons move through a barrier that they classically shouldn’t be able to move through. In classical terms, if you don’t have enough energy to move “over” a barrier, you won’t. However, in the quantum mechanical world, electrons have wavelike properties. These waves don’t end abruptly at a wall or barrier, but taper off quickly. If the barrier is thin enough, the probability function may extend into the next region, through the barrier! Because of the small probability of an electron being on the other side of the barrier, given enough electrons, some will indeed move through and appear on the other side. When an electron moves through the barrier in this fashion, it is called tunneling.

Quantum mechanics tells us that electrons have both wave and particle-like properties. Tunneling is an effect of the wavelike nature.

The top image shows us that when an electron (the wave) hits a barrier, the wave doesn’t abruptly end, but tapers off very quickly - exponentially. For a thick barrier, the wave doesn’t get past.

The bottom image shows the scenario if the barrier is quite thin (about a nanometer). Part of the wave does get through and therefore some electrons may appear on the other side of the barrier.

Because of the sharp decay of the probability function through the barrier, the number of electrons that will actually tunnel is very dependent upon the thickness of the barrier. The current through the barrier drops off exponentially with the barrier thickness
