If the book is very funny, as you claim, then it will not be a total loss of
money and time. 😉

I have a degree in Physics and I am sure I am suitably qualified to make that judgement.

I bet you got your degree by mail order, right?

Here is a simple Thermodynamics problem for you. second LAW.

A crane is operated by a 15 hp gas engine. Taking into account the heat
lost by friction in the crane, THE EFFICIENCY OF THE ENGINE IS 20%. If
the combustion value of the gas is 600 BTU per cubic foot, how many
cubic feet of gas must be used to lift 3000 pounds through a height of
60 feet?

Dr. Batten is a genuine scientist.

Well I suppose it is a genuine reference book in the sense that it's a book you can refer to, but rather like that Forbidden Archaeology book that Dasa was peddling it is totally unscientific. It doesn't try to weigh up the evidence, it doesn't look objectively at any of the issues raised, it just takes a tiny proportion of the data available in order to attempt to support an entirely unwarranted conclusion.

I had a quick look at the chapter on radiometric dating, and it confirmed my expectations. All of the issues he raises regarding supposed 'flaws' in various radiometric dating methods have been long since satisfactorily resolved. To take those issues and conclude, as he does, that the world is only a few thousand years old is just facile.

As for your claim that he is a genuine scientist, you're right up to a point. He does have a genuine qualification in plant physiology and the work he has done in this field appears to be valid and, as far as I can judge, worthwhile.

Incidentally, this book in it's entirety is available free as PDFs at:

Don't have time to do all the calculations for now, but quickly, 1hp (assuming metric) = 735.499 watts.

1 watt = 1 J s^-1

Note: ^ in this context is to the power of.

Therefore, this gas engine has a maximum power of 15 x 735.499 = 11.032 kW

Need to then convert pounds to metric (kg) and to work out the height, feet to meters and the potential energy required to lift:

P.E. = mgh

Where g = 9.81 ms^-2

Then work out how much energy from the cubic feet of gas, and take into account the 20% energy. Will come back to you about that but need to visit my parents for new years. 😛

This is something I can do EASILY 15 years after completing my degree.

Also, what is the point?

I wanted to know if I should take you seriously. However, I am an American
so there is no need to convert it to metric, you can just give me the answer
in cubic feet as I asked using the British Thermal Unit (BTU) I gave you.
Very simple calculation that way.

Come over to the chess forum and you can talk us through a couple of your games. I want to know if i can take your chess seriously?!

I am not interested in you taking me seriously in Chess. But I wished
you lived here close to me, so I could beat your butt over-the-board
playing real tournament chess. Then we could see who is serious.

I don't take you seriously full stop Ron, let alone in chess. I don't doubt you can play a good game, the question is how good a game?

I am getting old now and will be 68 in March. But I hope to join the
USCF again and play over-the board rated games. I am definitely
not a master, but I believe I can bring my old 1817 rating up to
at least the expert rating. We will just have to wait and see, for then
I want be able to move the peices around before I make a move in
the over-the-board play with the clocks.

At my parents now.

I convert to metric because that is the internationally recognised SI units (which will be metres, kg, Joules, Watts) that I am used to. Physicists work with SI units all the time and I am not as familiar with imperial units. It is normal for a physicist to convert all units to SI before doing their calculations. Even in the US, physicists will work with SI units.

I guess you got the problem from some engineering book or source which are specific to this kind of work and it is normal to work with BTU, pounds and cubic feet and certainly the standard formulae normally used will be simple with those units. However, with my background that is very unusual to me.

I certainly can calculate the answer in SI (in cubic metres) and convert that to cubic feet.

Although this is digressing as the argument is whether Don Batten (whose speciality is actually plant physiology) really understands thermodynamics.

Entropy does have overall increase in a closed system (i.e. the entire universe, assuming there isn't influence from other systems). In subsystems, while there will be pockets of increasing entropy, others can lose entropy.

I took my courses in physics before U.S. converted to teaching science
using the metric system although we did do conversions at that time.
I am an old fart of 67.

Fair enough. Happy new year!
