I'm a novice astronomer. I've only recently started out when I got a smallish Scope for Christmas. Can anyone guide me on the best Telescope you can buy? I'm looking for something that will interact with my Laptop, and ofcourse Software. I'm thinking it will probably me motorised, but gosh I've looked at catalogues, and it get's more confusing the more I look at it. Any tips from Home Astronomers serious about the game would be much appreciated.

Also, If I wanted to build an observatory on my property, do I need a licence or permit to do this?

Many thanks :)

Why don't the drug wars and put the drug dealers out of business? If they stop the killing, then they won't have nothing to fight over?

I used to smoke occasionally, only when I was with the "pot crowd" and I remember I had a drug screen just a few days after I smoked out once with my friends. I was all worried, but then a security guard guy (who I had smoked with, right inside the security booth) told me, "So? Just drink a jar of vinegar before the test."

That was all he said. A couple of days before the test, I looked in the refrigerator and found a jar of chili peppers in vinegar. I just drank 1/2 of the jar in one gulp, and downed the rest of it the next day.

The next day I had the test and everything was perfectly all right.

I'm telling this to my friend, who is to be drug-screened soon and he lives in an apartment with roommates who constantly smoke out--plus he himself recently went to Amsterdam and had pot muffins there.

He doesn't believe the thing about the vinegar, but I tell him it worked for me.

Any connoisseurs out there?

As for my friend, I don't want to give names, but his initials are Frank Chao.

I'm taking all pre-med and lower division class at community college , and then transfer to university. I'm gonna finish all pre-med course by next spring 2008. My question is, should I take MCAT right after I finish Pre-med course? or is it better to take after I transfer to University?
How long will MCAT score valid?
would medical school admission take any consideration if I take MCAT 2 years prior to apply?
thank you
p.s: pls answer seriously =)

We never did anything even close to this in class, and i cant find help in the textbook, im desperate, please help me...

"Small quantities of oxygen gas are sometimes generated by heating KClO3 in the presence of MnO2 as a catalyst:



2KClO3(s) → 2KCl(s) + 3O2(g)



What volume (ml) of O2 is collected over water at 20.0 oC by the reaction of 0.261 g of KClO3 if the barometric pressure is 722.7 mm Hg
The vapor pressure of water at 20.0 oC is 17.5 mm Hg. "

Someone told me that this is the correct was to do the problem, however the answer is incorrect, can someone please help me?

2 KClO3---> KCl + 3O2

the molecular weight of KClO3 is 122.5

so you can see that 2*122.5 = 245g of KClO3 corresponds to 3 moles of O2

0.261 g corresponds to 0.261*3/122.5 = 0.064 moles of O2

to calculate the volume you use the formula pV = nRT ;
T = 293 K and 1mmHg = 133 Pa

V = 0.064*8.31 * 293/ 722.7*133 =0.0016m^3 = 1.6 liter

we have 200, four-hundred pound men, sitting inside a bus traveling at 200 miles per hour, (the men are seat-belted of course for safety reasons)
if one these men falls out of the bus at the 100 mile mark, thus increasing the bus speed to 225 miles per hour, how long will it take this bus to travel 400 miles???
