Dictionaries define the word ’doctor’ as ‘learned’, ‘teacher’, ‘most highly qualified’ etc. However, at least in our country, doctors are among the most ignorant. It may be natural for a doctor not to know much about hydro-geology. It may be possible for him not to be aware of the latest breakthroughs in astro-physics. But for a doctor not know much about Medicine, or not to be aware of the developments in his specialty is not only untenable, but also dangerous and criminal. Yet, there are thousands of doctors in our country who do not know much about Medicine, as it is practised today. Most of these doctors, it will be surprising to know, are very busy practitioners. I personally know of professors of Medicine who advise patients of Rheumatoid Arthritis to get Ayurvedic help since there is no drug in Modern Medicine (still erroneously and unfortunately called Allopathy, meaning “approximate”) for this disease. This is when even the most basic of textbooks of Medicine has a few pages discussing the drugs available for the treatment of this disease. Of course, the treatment of Rheumatoid Arthritis, like that of most other medical illnesses, is developing and improving continually.

“Harrison’s Principles of Internal Medicine”, the most trusted and respected resource on General Medicine all over the world, says, “Medicine is an ever-changing science.” It is estimated that about 50% of the medical knowledge is replaced by new, scientifically researched, proven and more robust information every ten years. This would mean that a person who qualified ten years ago and since has not tried to update his knowledge is 50% outdated. He may be more dangerous than the diseases that he treats!

One important contribution for ignorant doctors come from private medical colleges. People purchase their degrees from these business institutions. Not much is taught or learned in most of these places.

Paradoxically, it is frequently a blessing for a doctor not to know much. If one knows enough and well, relevant differential diagnoses (the other likely possibilities that must be excluded) will come to the mind when seeing a patient. It may make investigating and treating rather difficult, given the peculiar milieu of our country.

It is important to introduce new legislation that makes it compulsory for doctors to renew their license every year after passing an examination designed to prove that their medical knowledge is up-to-date. It is unclear why the Government are reluctant to make any move in this direction, though one can make a few guesses.

Ok I have to come up with a conclusion to my theory that you can make a hot dog tarvel through time in a microwave. So I put a hot dog in the microwave and watched spin around for several mins in hopes that it would travel through the vectors time.

I'm in high school, but I still can't pass Pre Algebra. I got a worksheet today, but I don't understand it. No, I'm not asking you to do my homework, I'm just asking for help.
The worksheet says:
For this task you will use deductive reasoning to determine which of the digits from 0 to 9 each of the letters represents. Each of the digits from 0 to 9 is used exactly once.

1. g + g + g = d

2. j + e = j

3. g times g= d

4. b + g = d

5. f - b = c

6. a x c = a

I kind of understand the instuctions, from what I understand you have to figure out what the letters are and what number they are. But I can't figure out how to do it. =[

Thanks in advance.

---------- +7x

is a building's height a vector? because it's going in an upward direction right...? unless there are slanted buildings... or is that just considered scalar?

The temperature at 0800 is -3 degree celsius
The temperature at 1400 is 15 degree celsius.

(a) Find the difference between the two temperatures.

The answer is 15 - (-3) = 15 +3
= 18 degree celsius.

Why must I take the temp at 1400 minus the temp at 0800 instead of the other way round which is -3 - (15) = -18? Explain please?

(b) Assuming that the temp rises at a steady rate, find the temperature at 1220.

Please show your workings clearly and explain, thanks a lot! :)

I've had this question on my mind for the longest of times. Since chickens are females and they periodically release unfertilized eggs, are those eggs considered periods?
^_^ please do answer, I'd love to mess with my friends with this one.

Okay, I feel REALLY stupid for asking this, but I just can't figure it out. I need to perform a calculation on a number in order to get the desired result, but every time I try, I keep getting the opposite of what I want.

Here are some test examples:

Number = 5,000
Result = 200

Number = 10,000
Result = 100

Number = 20,000
Result = 50

Number = 40,000
Result = 25

etc.

Can anyone think of a formula to convert the number into the result?

Thanks!
