1. These investigations of the sun's luminosity are not just intellectual curiosity.
2. Stand magnifiers overcome this problem as they are mounted on supports that ensure the correct viewing distance, and some have built-in illumination to increase the luminosity on the working surface.
3. I now enhance and accentuate this be establishing the light tones of background wall and the luminosity of the foliage created by the back-lighting.
4. As the Sun's rotation brings a large spot, or group of spots, around to face the Earth, the sun's luminosity falls by 0.1 or 0.2 per cent.
5. I sat for what seemed a long time in the cold darkness, breathing shallowly, not moving at all, just waiting, and eventually there was a lightening of the shadows and a luminosity in the wood, and the moon rose clear and bright in the east.
6. It resolves the puzzle of why the Earth cooled even while the concentration of carbon dioxide was continuing to grow exponentially, and all it requires is a peak change in solar luminosity of just 0.28 per cent over the 76-year cycle, producing a maximum influence on surface temperatures on Earth of only 0.28C.
7. So the changes in the spectral lines tell us of changes in the Sun's temperature, which in turn reveal changes in the solar luminosity.
8. This creates a pronounced visual luminosity and shows up on the X-ray as strong white.
9. In a recent book they pointed out that the laws of physics dictate that the sun's luminosity must have increased by 30 per cent during the past four million years.
10. But the longer-term variations cannot be due directly to sunspots, The most recent peak in the number of sunspots, the period known as the solar maximum, was in 1979 - yet according to Livingston solar luminosity was at its lowest two years later, in 1981.
11. The Sun's luminosity is proportional to the fourth power of its temperature, according to Stefan's law.
12. The architects of the Gothic period exploited this device to the full, for they recognised that greater religious impact could be made by stressing the luminosity and verticality which result form its adoption.
