As a college student, you can familiarize yourself with ways to conserve the environment, appreciate policies that advocate for a change in natural resource allocation, and apply your skills to conserve the ecology.
A new Born Free report is busting the myths and exposing the cruelty behind trophy hunting, starting with the claim that it can actually benefit wildlife conser
Thanks to the horse meat scandal tons of processed meat products are being removed from supermarket cabinets. The waste is huge. But the meat industry usually strives to avoid waste. Any part of an animal that can possibly be used for human consumption is made fit to eat, right down to the stripping... Read more
Andrejs Skuja  asked the Naked Scientists:    Hi Chris, I have a query I’d love answered if possible. I was recently posed the question, ’Why do our s...
Don’t let the below commenters put you off. Angular momentum is just as real for quantum particles, you just have to quantize it first. I like your idea, so do many very highly respected physicists.
you sure? “When an electron moves from a higher orbital to a lower orbital, the atom emits a photon. … Angular momentum is conserved only if there’s no external forces, in this case the electron gains energy by light or by heat wich is kinetic energy.”
Is the conservation of angular momentum violated in electron jumps from one orbital to another?
I don’t really know any quantum mechanics. But in our class, we were introduced to Bohr’s model of the atom with his postulate that the angular momentum of an electron in the $n$-th orbit is $frac...
Hmmm, i can see how a simplistic view of conservation of energy indicates that “the closer you get, the faster you go” but I think the analogy ends there. Electrons don’t even actually orbit the center of atoms, that was just a way to explain it, way back. Sorry.
Here is the Q and A Carroll published a few days later. Goes into more detail on some points. He is a great explainer – just what we need right now – especially in confused qm physics.
Great video, explains a lot and I didn’t realise it but yeah, conservation of momentum and energy are great ideas it would take a while to fully getting to grips with.
Green school programs might be the only hope of preventing future environmental crises.
There are several eco-school programs around the world aimed at teaching kids how to care for the environment.
Environmental education can be more effective at tackling pollution by preventing it in the first place.

Anyone making an argument for trophy hunting is living in their own little world. This barbaric practice should be banned completely!

Trophy hunting has become too widespread. We need some fresh thinking to curtail it.
What a creative idea; I doubt many people would survive these animal encounters.
Truth is worse than fiction. Watch the video from this story here https://www.youtube.com/watch?v=rgAYhwluHOs
I thought this idea was a joke, but…
Nice idea if it helps but sounds like it could be a way to just landfill dump animal carcasses in the sea. So not good.
urr, yeah, but what do you do with the rest. every day!
How to save coral reefs? Same as saving anything, keep humans the hell away from them.
Angular momentum, in the form of “spin” is transferred to or from the photon. but read this to get a better idea of what you are trying to say… https://www.thenakedscientists.com/forum/index.php?topic=35361.0

Khan Academy also cover it. So fundamental, its easy to miss completely before getting into more complex physical ideas
