The traditional mathematical foundation of the Aramaic calendars within the useless Sea Scrolls is analysed during this research. Helen R. Jacobus re-examines an Aramaic zodiac calendar with a thunder divination textual content (4Q318) and the calendar from the Aramaic Astronomical booklet (4Q208 - 4Q209), all from Qumran. Jacobus demonstrates that 4Q318 is an ancestor of the Jewish calendar at the present time and that it is helping us to appreciate 4Q208 - 4Q209.

This aerial picked up radio-waves only on the side it was facing. The radio-astronomers pointed their aerials in various directions. It appeared that radio-waves radiate from all warm objects. Of course, these waves do not carry words or music. If you catch them and feed them into a loud-speaker, you will, only hear a rustling sound. But this rustling sound varies according to the object's temperature. Radio-astronomers learnt to distinguish these sounds and measure the objects' temperature from a distance.
Jupiter and its moo~s are very like a "mini-Solar System ". good idea of our family of planets with the Sun in the centre. Saturn is also like a bright white star but it shines slightly less than Jupiter. U o • It is the most beautiful planet-you'll see why later on. If we could gather together the planets and line them up against an enormous ruler, we would see that they are all of different sizes. Some are smaller than our Earth and others are much l~rger. Mercury is the smallest planet and Jupiter is the largest, but even Jupiter is many times smaller than the Sun which could not even be fitted on our drawing.
Some are smaller than our Earth and others are much l~rger. Mercury is the smallest planet and Jupiter is the largest, but even Jupiter is many times smaller than the Sun which could not even be fitted on our drawing. We've drawn the Moon by its side as a guide-line. It is even smaller than Mercury. Do you see how different all the planets are? But do you think it makes any difference which planet you live on - on a small one or a big one? ' There's more space? Or on a small one? You can get "around the world" quicker?
