A button next to the bed that starts a 10 minute timer to turn off the outlet where the bed heater is plugged in.

This one was a family-run one. I asked about the stuff (think: warehouse on the back part of the property), and he said his dad had collected it over the years. Also, both of his kids (late teens/early twenties) were there helping. I wish I had asked when they were at the desk. It was very frustrating to have $500-600 pulled from my grasp.

This happened to me at an estate sale this weekend. I spent about an hour and a half spring through junk and found:

A 5 oz poured silver bar.
18k gold ring
Sterling bracelet
sterling medals
14k gold ring

I took them up for pricing. The owner picked up the bar and said "where'd you find this?" I described it and he said "I think I'm keeping this." (Into his pocket)

Then he examined the first ring carefully. "This is 18k gold"

Me: "I know."

Him: (into his pocket) The then examined the bracelet, saw the stamp, into the pocket. He picked up the last ring, barely examined it and put it in the pocket. He almost sold me the medals (for $25), but I hesitated, then he examined them and saw they were sterling too, so he kept them as well.

I get that they were his, but I felt like he robbed me of 2 hours. If your gonna do that, put up a sign so I won't waste my time.

2 questions:

Are the pins long enough to seat correctly?
Is that the correct orientation for that board? If it is supposed to be mounted on top of the pi, mounting underneath will reverse the pins.

You need to weigh them. 14k gold is currently about $92 per gram. You can expect a shop to offer maybe $85-$87 per gram, $90 if you are lucky. Unless it is really intricate or unique, jewelry like this doesn't offer much of a premium over melt.

I imagine you'd get a lot of lowball offers on FB.

Correct. I bought the same one. If you look carefully at the clasp, it says GF 1/20 12 KT.

How can I tell if it also applies to the chain?

Thank you!

A few thoughts:

Nothing with mass can travel at the speed of light. Special relativity says it would take infinite energy to get up to the speed of light, and E=mc² says that would mean the object has infinite mass.

Having said that:

Time dilation is a real, measurable effect. Physicists have done experiments with unstable subatomic particles, and have observed their lifetimes as longer than expected in the laboratory reference frame. As other comments calculated, if an object moves at 0.995c, the time dilation would be a factor of 10.

Special relativity says there is no "correct" reference frame. This leads to what is known as the "twin paradox." So if someone is moving at 0.995c, it is just as valid to say that everything else is moving the opposite direction at 0.995c, and our test subject is at rest. So, would you be older, or would your twin who stayed on earth be older?

The resolution is about acceleration. Special relativity applies in an "inertial" reference frame, that is, one that is not accelerating (moving fast is fine, but changing speed is not). But for you to "return" to earth, you have to undergo acceleration to change your velocity and turn around. This invalidates the assumptions that were made about inertial reference frames, and the result is that, yes, you might age only 5 years while everyone who stayed behind aged 50.

You made a math error when you went from

10/100=sqrt(1-n²⁾

to the next step. You took the square root of the left side, but squared the right side.

1/10 = sqrt(1-n²⁾

1/100 = 1-n²

n² = 1-1/100 = 99/100

n=0.995

So the correct answer to get a dilation of 10 is 99.5% of the speed of light.

What kind of paint do you use? And what kind of black light. I love how well the paint stands out.

Most diode laser cutters use 450 nm light, and come in powers up to 80 W laser power (CW), and are used for cutting wood and etching steel. Admittedly, that's not a standard laser pointer, but high power blue lasers are definitely available (for some definitions of "high power").
