Hi. I tried to make a homemade solenoid and it sucks. The copper has tight little humps in it and it wants to spring out of the compressed coil configuration instead of staying compressed onto the iron. I looked on youtube but I haven't found any good tutorials yet. What is the best way to make...

Windows 10 v1909 is a feature update rather than a security update. Although it was not compulsory to upgrade, I decided to do it - getting something for free, who wants to decline it? I plugged in the laptop and it installed overnight. In the morning, I found that the upgrade was complete...

Is it not Spacetime is akin to the Wave function in Quantum Mechanics where it is just a mathematical tool and no way to distinguish between different interpretations? Why is that there are countless professional debates about interpretations of quantum mechanics while there is very few or...

I keep seeing these pods along the sidelines of the professional soccer fields on TV (pro footbol pitches), and I'm wondering what they are for. There seem to be more of them at the ends of the field, and especially near the goals. Are they microphones? If so, what are they for? Who hears...
