Science & Mathematics - 17 February 2007

When I was a child I had a head injury that required a CT scan. The neurologist pointed out that my brain stem is reversed (it curves toward the front of my skull instead of curving back). I recently had another CT scan and the doctor mentioned the same thing but I was so out of it during both hospital visits I never got the chance to ask.

Does it mean anything? Would this cause any differences in brain function or general wiring? It isn't bad is it? Is it very uncommon?

I know that I asked several related questions there but I've always been curious about it!

The other day at college my math tutor gave me this question, and it did it, and to my tutor's surprise i had got it right. She said that this was an extremely difficult question and that the average person couldn't do it.

I need proof before i can believe her, so below is the question she gave me.. Try it out and see if you get it right.

An arithmetic progression is such that the eighth term is twice the second term and the 11th term is 18.

Find the smallest term of progression whose value exceeds 126.

{Common difference = 1.2 and first term= 6 the 26th term= 546}

3 people went to a hotel. The bill was Rs. 70. They pay Rs. 25 each, so the total is Rs. 75. Waiter keeps 2 rupees as tip and returns 1 rupee to each. So each of them pay Rs. 24. Now 24*3 is Rs. 72. Waiter tips Rs. 2. So Rs 72+2=74. Balance 1 rupee. Where it is? If u r a brilliant answer this. !!!!

This phenomenon my occur all the time, I don't know, but I only notice it when its super cold out. What I am referring to is say the temperature is -1 Fahrenheit. Just before the sun rises I notice the thermometer drops a couple of degrees, to like -2, or -3. Then of course once the sun comes up the temperature begins to rise. I've asked several people that I consider pretty smart and nobody seems to have an answer.
