When you close your eyes and visualize E=mc2 in nature without math, what images do you see?
I always saw the Hiroshima mushroom cloud, but after reading your posts, I agree bombs are not the right image when introducing concept to kids.
1. I now see star core nuclear fusion of hydrogen into helium as the best visual of E=mc2. Agree? What you see?
2. Is starlight most obvious example of E=mc2? Can we say stars shine for billions of years entirely because of E=mc2?
3. If Starship Enterprise transporter transported a kilogram of star core onto the transporter pad, what would we see? Solid, liquid or gas? Glowing or dark? How radioactive would this star core goop be? How hot would the goop be and how long would it remain hot? Removed from star core pressure, would this goop just be a harmless inert puddle?
4. Atomic bomb is fission, star core is fusion, but is a hydrogen bomb explosion more fusion than fission?
I misunderstood C2 as lightspeed so saw it involving Han Solo or Captain James T. Kirk going warp speed. After reading your posts I see C2 is not about travel or light, but about potential energy. It is easier for me to now see C2 as Universal Constant Squared, to avoid Star Trek images.
As a humanities teacher, I can easily teach most high school astrophysics. Kepler and Newton are easy. Einstein is much harder. I avoid math, but E=mc2 is too important to ignore.
I'm a huge fan of Carl Sagan's COSMOS and Neil Degrasse Tyson. Sagan's last interviews before dying lamented most Americans no longer understand technology we depend upon: TV, radio, lightwaves, electricity, nukes, computer software is all a total mystery to 90% of the public. That is dangerous, as Sagan says: "If we don't understand our world, then we are just putty in the hands of those in power."
Take a look at Sun video below: It is exactly what I've been asking for, the kind of simple stuff anyone can understand, using props and toys. When this Australian dude smashes wet sponges together, even the girl who didn't understand suddenly understands water splashing out is the Energy that starts solar convection that results in sunlight photons.
Know any more easy youtube videos to introduce astrophysics?
