Light Tabletop Desk
Can you use a fluorescent light bulb in a desk lamp?
I'm going to start some seedlings indoors soon and can't afford to purchase a gardening lamp. Could I put a fluorescent light bulb in my tabletop desk lamp?
You can get a compact fluorescent bulb like a CFL that will fit your lamp and get it to turn on in your desk lamp. The problem is that it will not contain all the sunlight colors that your plant needs to grow.
You would be better off buying a non-fluorescent "Gro-Lamp" bulb that does have the proper light spectrum and using that in your desk lamp. They are only a few bucks. You don't have to buy a huge fluorescent fixture for that purpose.

Faster than light disturbance?
Take a water bottle. You have it upside down on a tabletop (cap touching the desk). If you keep the cap in the same spot, and lean it to the left, and then to the right, and back and forth, is this not a faster than light disturbance? You move one end of the bottle, and the other end responds instantly...what am I missing?
It doesn't respond instantaneously.
In small distances like this, it seems immediate, but if you were working over long distances, you would see that the movement occurs at the speed of sound in the material.
Traditional question involves a very long rod, and you twist on end or push one end and expect the other end to move immediately. It doesn't, there is a delay.
