I am supposed to reach a lux level of 750 in a room.

I have chandeliers and downlights installed.

Depending on where you are in the room, whether you are standing or sitting down; where do they mean when they say - recommended lux level is 750, does that mean right below the light, at desk level, standing right below a downlight, average light in the room?

if you know, pls inform me.

thanks

As a newlywed living far from home in Lisbon, Portugal, I was awakened during the middle of the night.......the sound of buildings heaving against the tremors....the sound of things crashing to the floor....the floor moving under my feet. I was terrified and ever since, I have been unable to step on uneven ground. I can still feel the overwhelming sense of being unable to control anything....not knowing what to do and where to go....35 years later it still haunts me. My daughter now lives in Los angeles and I have nightmares about her being caught in an earthquake. If you experienced a similiar situation, has it had a long-term affect on you?

prove: if x^2 = n (mod 65) has a solution (for x), then x^2 = -n (mod 65) has a solution.

(the "=" are congruence symbols.)

The word "quad" usually stands for 4 of some thing. An example would be quadruplets - 4 babies. So I am wondering why they use the word quadratic in Algebra (the Quadratic Equation) when the polynomial is only a second-degree polynomial, meaning the highest exponent is to the second power. Why is this?

I heard these numbers somewhere at school.

About 10% of the population is left-handed. About 10% of the population is gay. About 2% of the population is both gay and left-handed.

Does that mean being left-handed decreases your chances of being gay?

I'm only asking statistically I really don't care about your opinions on gays or lefties.

I don't know if other countries use them more, but I see very few solar panels in the U.S. and most of them are neglected and broken. Technology has come a long way, why aren't we putting sunshine to better use? It makes more sense to me than a windmill, and I see those things popping up quite a bit.
