What Do You Mean Mass is Energy?

As a kid I had no idea what it meant when I was told "Mass is Energy" and "Mass can be converted into energy". No matter how many times someone repeated that "They are just the same thing" it didn't click.
Well hopefully this can clear things up to younger me.

Perhaps the real connection between mass and energy is the point of reference we made along the way

I like the use of visualization. Even though the subject as a whole is still pretty obscure and incredibly complex to me, every bit of simplification and visualization helps me comprehend, or at least discover, just a little bit more. Not that I've hopes or desires to ever fully understand the whole universe, but the more little things I know makes me more comfortable in it. Nice videos!

Nope, I have to admit that I don’t understand this.

The clearest thing I got from the video was how two seemingly different waves were actually the same but one was simply moving and the other was stationary. I'll take that as an accomplishment.

Your videos are magical for me. You always pick a topic that has been explained before by other educational channels and then time and time again surprise me by showing me how much I didn't know or consider. And you explain it incredibly well.

HEY WHERE IS THAT SECOND VIDEO!? YOU PROMISED US SO YOU WILL DELIVER.. OR I WILL GIVE YOU SOME HYDROGEN IONS!!

Holy shit

That was disturbingly deep and simple at the same time. Great work!

This was a very insightful video. I'm learning more and more about the fundamental physics of the universe with each one. Also, the Higgs field speaking Spanish totally caught me off guard 😂😂

[@lancelotthefallen763]

This channel is so underrated yet the best to explain such curious yet hard concepts with such dephful yet understandable and soothing explanations. Hope it gets the recognition it deserves soon.

[@auspistic]

I think there's one aspect here that is helpful as well: remembering that we want to think about

[@MolecularMachine]

I love, love, love these videos. I consume all kinds of layperson astrophysics and quantum mechanics material, but your channel and Arvin Ash's are the two that really make things click. Bravo! You answer these confusing questions with clarity and style.

[@inderjeet7633]

I ABSOLUTELY love your videos. whenever you upload I settle in before watching. The science is accurate making the concepts super clear. If you've ever wondered that whether your videos are doing what they're supposed to.... They totally are. Thank you.

I would love a video on quantum field theory, anti-particles, quarks, leptons and bosons, and ways that they all interact with one another. The visual of the quarks being "held together" by gluons, or rather absence of gluons in between was like a missing puzzle piece of understanding.
