Science & Mathematics - 2 November 2007

Starting with the elements on the Periodic Table, every molecule, water, and any source of energy that you need (wind, water, fire, solar, etc.) could you build a human being from scratch and then make him or her come alive? Or any other living organism? Money is no object either. I'll give you unlimited funds. Could you do it? It's not that hard to do. After all if evolution is true, dumb luck and blind chance made it happen. You're not stupider than dumb luck and blind chance are you? If you are, by your own admission, stupider than dumb luck and blind chance, then why would any thinking person take your theory seriously? Even if you have studied and learned a lot about science.

"When" the USA put a man on the moon, can anyone please explain why there were no stars in the pictures? Our atmosphere stops us seeing most of whats there but away from cities and the street lighting etc, you can see billions of them. Surely on the moon you should see even more?
Also, how did the astronauts survive the tremendous radiation without suffering radiation sickness/burns etc. I was taught that getting through the Van Allen belt would probably kill someone and cosmic rays when sun spot activity was so high would undoubtedly have finished them off.
I'm not a conspiracy theorist, just someone who cant work out the above problems.
Please don't rant as most from USA usally do, just explain in rational terms.

What planets will really align in 2012. Venus,Mercury,saturn.
What happens when the suns new 24th 'sun spot' change thing happens?
And just basically what will happen 2012 comes threw?
Will the maya calender really end, or a new cycle of sorts starts?
If it does end, Why?
What does NASA and the GOVERNMENT(s) think of this?

What does Nostradamus really predict about 2012?, and not what the media is hyping up about it.

ive done the enzyme essay expt both purified and crude ones.
i need to get specific activity and i have done it
bt i am not so sure about it so plz check my answers
and if its wrong plz correct me!!

Activity of the purified enzyme
ΔAbs /min of 0.538
[got if from the spec with 400nm]
From Beer-Lambert Law A= εcl;
0.538=18300c ∴ c= 0.0000294 mol/l =0.0294mmol/l =0.0294umol/ml
The cuvette volume was 4mls
∴ 0.1ml AP transformed 0.1176umol pNPP per min
∴ 1ml AP 1.176 umol pNPP per min.
∴ the activity of the enzyme is 1.176 IU/ml enzyme.
Activity of the crude enzyme
ΔAbs /min of 0.320
A= εcl → 0.320=18300c ∴c=0.0000175 mol/l = 0.0175mmol/l=0.0175umol/ml
The cuvette volume was 4mls
∴ 0.1ml of crude enzyme transformed 0.07umol pNNP per min
∴ 1ml of crude enzyme 0.7umol pNPP per min
∴ the activity of the enzyme is 0.7 IU/ml enzyme



protein conc for crude is 13.6mg/ml
protein conc for purified is 0.05mg/ml

i dnt know if i need to use those protein conc figures!!

If we could travel at the speed of light, it would be possible to escape time thereby negating the concepts of hours, minutes ~ years. Thus we could move from anywhere to anywhere in an quantified instant, making the most distant parts of this universe just a hop, skip and a jump away (minus the skip and the jump). Am I looking at all that correctly?

And how far are we from achieving that, short of a monumental breakthrough Quantum Physics?

Here's the idea: Time does not exist. The universe is made up of cycles things die and things are born. There is no such thing as a beginning or an end. For example, a seed is planted and grows the plant dies but it has planted more seeds. The universe never began, it just always existed.. The world is recycling constantly, all elements of space and all atoms are recycled, atoms are shared...

An item costs $200 at time t = 0 and costs $P in year t. When inflation is r% per year, the price is given by the following equation:
P= 200e ^ rt/100
a) If r is a constant, at what rate is the price rising (in dollars per year) initially? At what rate is the price rising after 2 years?

b) Now suppose that r is increasing by 0.3 per year when r = 5 and t = 2. At what rate (dollars per year) is the price increasing at that time?
