Why can't we have nice simple physics anymore
« on: 25/03/2011 16:20:42 »
Why can't we have nice simple physics anymore ?, when I was at school the only subatomic particles were Protons and electrons, no neutrons, gluons or anti particles and what not and nuclei were solid masses of protons and electrons with solid electrons ziping round them.
There was only one galaxy and a nice dense Šther to carry the light waves and 'radiation' was benificial.

Because scientists are too curious to have nice things.

In one sense, today's physics is simpler.  Many formerly unrelated physical laws have been tied together.  However, the mathematics behind it is much more difficult.

Syhprum - I had surmised you were one of the elder statesmen of the forum, but the neutron was postulated in 1920 and confirmed in 1932!  And SR and other work of the early 20thC kind of did away with the need for the Šther (I had to copy and paste to get the nice synaeresis symbol).

I agree with JP it's got much more complicated in some terms, but much simpler in others - concepts of symmetries and conservations, unifications, etc

I was in school during the war our text books dated from the twenties and Our teachers knew little or nothing about physics.
I was in a so called technical school and the object was to train us as technicians for the local paper mill or navel dockyard

PS just use ALT 145 for Š

Š  - oh yeah.  Very cool!  Paper Mill/Naval Dockyard = Kent ? 

I would be curious what maths you were taught - my parents are the same generation and I am astounded at the gaps in their maths.  Very heavy duty calculations and mental arithmetic but little to no calculus, very basic trig, no linear algebra etc

We were taught Trigonometry up to a fairly basic level such as would be useful for navigation, much exorcise in the use of logarithms in a rather strange way where the logs consisted in separate integer parts (both pos and neg) and a decimal part !.
Slide rules were all the fashion for arithmetic.
Algebra up to quadratics and simultaneous equations (no mention of "i"), the basic school ended at the age of fourteen but bright ones could stay on another year and learn a little bit of calculus by rote but no applications.
The most boring subject was drafting with very simple equipment,we also did metal working with olde worlde belt driven lathes and wood working with quite modern equipment directed to pattern making.
I think most of our text books were those thrown out by the local grammar school hence the lack of modern physics.
My elder sister went to the local grammar school where the head mistress had the forsight to see that they were taught German!

PS my father was very proud to be able to work out square roots by a sort of reverse binominal method.

I always loved those old steam locomotives, i know they spewed out some CO2 but sh* how about our cars today huh :). And the way the wagons opened on the side to allow people out and in, and the wooden benches. I don't think it was more uncomfortable then than it is now traveling. At least the trains had toilets. Sorry Syhprum, got almost nostalgic reading you :)

And, you could open the windows too :)

I prefer the DB ICE that wafts you along at 300 kph

Which raises an interesting question. If I convert my truck into a wood fired steam engine that belches soot and CO2 all over the place, is it "greener" than my neighbour's electric car?

This car seems quite green: http://news.cnet.com/8301-11386_3-10317389-76.html

At least the paint job.

Well, park it beside his and, rev it up :)
See what he thinks, when he's stopped sputtering, invite him to a race :)

Didn't Howard Hughes build a steam car too?
