Isn`t there a way to (RALLY) the country together to fight the gas prices? They go up on weekends and holidays., also makes no sense that every station or conv. store you pass has diff. price.
Same thing holds true for power companies, up in summer time., Tired of getting the shaft and finding it very hard to make ends meet., Prices go up (* pay dosn`t*).

Can you create a young's fringe pattern using two lasers of the same type, with fairly divergent beams, in place of the single source and two slits, commonly used to create this type of pattern? How?

Reading level should indicate that it's something a doctor would use -- use both brand names & ingredient names of drugs, side effects, interactions w/ other drugs & substances, etc. Should be scientific & informative.

If there's no such website, then perhaps there's a written form somewhere or a way to request such info from drug companies/pharmacies w/o being prescribed the drug as a mandatory precursor for such knowledge.

Thanks.

For combinations question, why do you times but not add up?
e.g 6C3 * 4C2=120, why is it not 6C3 + 4C2 ?
It's so confusing.
Please explain clearly.
