Light absorption and color confuses me. Electrons absorb photon energy at certain frequencies, and the light that's not absorbed is reflected and that gives the color, but doesn't the energy get emitted again with the same frequency? So, the emitted and reflected photons would add together to give back the original color of the light rather than the object. Why doesn't that mean everything is the same color?

#breakfast : scrambled eggs with kale, parsley, jalapenos, garlic, and mushrooms
+ oatmeal with honey, PB, banana and my secret blend of spices 😋

Baked potatoes, jalapeno, garlic, parsley and zucchini. One of my weirder late night meals

@lupyuen the teased video of all submissions is ridiculous though - 3.5 hours of just bipeds walking, hunched, rightwards? You'd have to be insane to want to watch that. Maybe it'd be cool to have it looping on a wall or something

@izaya oh heck no. might want to have a frank discussion about boundaries.
(I wouldn't even throw out a roommate's food if it was moldy as long it was in a tightly sealed container. You just don't screw with people's stuff like that.)

@izaya are they throwing out *your* food when it's past-date?

@AmpBenzScientist sure... you know how my education went, person I've never met /s

I did learn proofs, and they are important, but for calculus specifically there are things like path integrals and Taylor series that were introduced in a way that just made me think, "why would you think to do that? why that way?" Back then, I didn't see the connection to real things and little time was spent on the mapping to physics, so the calculus that was used in physics was inscrutable to me.

That's my take right now anyway. Science and math education isn't easy or universal -- different students need different things at different times. Maybe it would have been just as difficult to learn *back then* even with the refocus I proposed. The physics interests me more now because I'm interested in optics and that for reasons I didn't have in high school or early in my undergrad.

I wish my high school and undergraduate courses had taught #calculus through the lens of #physics instead of keeping it all abstract. I'm relearning a lot of it now that way, and it actually makes sense and "sticks" because the equations describe real things and I have a reason to know them.

@top tbh, I didn't see hardly any posts from this account since I followed. What was the value proposition in setting up a musiq.fan account if I already have a Mastodon account elsewhere?

I notice some recent images delivered from the #Perseverance rover were actually captured much earlier on in the mission. How do they prioritize image dissemination and upload in their processing chain, I wonder... Presumably they favor sending images of scientific relevance and for operational status, hence more images of soil, rock, and the rover itself. Seeing the parachute from below may be useful, but maybe not needed as much since they'd already landed.

@PawelK I didn't say it's immoral. It's like, there's a presumption that if you're reaching out to me on LinkedIn it's because we share common interests related to our work and you want to develop a professional relationship on that basis. In the story of the Arabic-speaking woman in the article, the man seems to have assumed they were starting a non-professional relationship which is inappropriate *unless* both people indicate unambiguously that's where they want to go. Given the woman's reactions, I don't think that was the case.
@freemo @lupyuen

@freemo LinkedIn is a site for *professional* networking, so trying to initiate romantic relationships from there is inappropriate from the start @lupyuen

@jeko I'm surprised. Is that widespread in the project or just something you and the other dev set up? Would think you'd have different preferred editors or at least key bindings

@jeko pretty basic question: I assume you're screen sharing, you take turns "driving", and you each write code on your own machines. If that's all correct, then what do you do to switch off between "navigator" and "driver" roles to keep context and keep in sync?
