How did I buy at 150 at the open market then?

Uuhhh, so, on your second paragraph: pebble

I don’t own one, I don’t know if I want one, but it is exactly that: a e-ink display for time and notifications

As it should be

wash your bedding once a month, or after a spill or accident

for the love of god don’t tell me you only wash your bedding once a month 🤢

Everywhere along its path at once*

They have momentum, but not mass (ignore the other explanation, like yes, E=sqrt(m0^2 c^4 + (pc)^2), but so what? m0=0 for photons)

As you can see, momentum, p, is p=E/c, and we know that the energy for light is proportional to its frequency, f, E=hf (h is Plank’s constant). So, p=hf/c. When light is absorbed by a material momentum (and energy) conservation apply and it imparts p onto the object. If light is reflected it imparts 2*p, showing this is left as an exercize to the reader

That’s for reccrding audio, iirc. Much more defensible and protects the little guy more. Eg, recording a meeting with an asshole boss

The 1st day of the feek is not universal. I grew up with the week starting on sunday
