5.3 Stellar astrophysics

If tunnelling out of nuclei is possible then so is tunnelling in! As a consequence it is possible to trigger nuclear reactions with protons of much lower energy than would be needed to climb over the full height of the Coulomb barrier. This was the principle used by J.D. Cockcroft and E.T.S. Walton in 1932 when they caused lithium-7 nuclei to split into pairs of alpha particles by bombarding them with high-energy protons. Their achievement won them the 1951 Nobel prize for physics. The same p

7 Subtracting decimals by lining them up

Subtracting whole numbers such as 52 from 375 is fairly straightforward. Subtracting decimal numbers such as 6.892 from 223.6 uses the same process but with one extra step – you have to line the decimal points up first.

Rather than arranging your two numbers so that they line up on the right-hand side, you need to line up the decimal points, regardless of how many numbers there are after the decimal point. In the example below, the top number has one number after the decimal point. It

Cost of Elections
Whether a candidate is campaigning for the presidency, the Senate, or for the House of Representatives, running for public office can be costly. It is rare for an individual to run a successful campaign by merely collecting signatures and placing his or her name on a ballot. Candidates who want to inform voters about their platforms must spend money on a campaign. (Video is narrated with slides and speeches.)

io = add 'isco'

tu = add 'isci'

Lei/lui/lei = add 'isce'

noi = add 'iamo'

voi = add 'ite'

loro = add 'iscono'

Then to conjugate the verb 'capire':

io capisco

tu capisci

Lei/lui/lei capisce

noi capiamo

voi capite

Doing Science in the Open
The internet is causing a radical change in how science is done. In this talk, Michael Nielsen, will describe how mass online collaborations are being used to prove mathematical theorems; how online markets are allowing scientific problems to be outsourced; and how online citizen science projects are enabling amateurs to make scientific discoveries. These and other projects show how we can use online tools to amplify our collective intelligence, and so extend our scientific problem-solving abi
