About the book Astronomical Algorithms

In the field of celestial calculations, Jean Meeus has enjoyed wide acclaim and respect since long before microcomputers and pocket calculators appeared on the market. When he brought out his Astronomical Formulae for Calculators in 1979, it was practically the only book of its genre. It quickly became the "source among sources," even for other writers in the field. Many of them have warmly acknowledged their debt (or should have), citing the unparalleled clarity of his instructions and the rigor of his methods.

And now this Belgian astronomer has outdone himself yet again with Astronomical Algorithms! Virtually every previous handbook on celestial calculations (including his own earlier work) was forced to rely on formulae for the Sun, Moon, and planets that were developed in the last century — or at least before 1920. The past 10 years, however, have seen a stunning revolution in how the world's major observatories produce their almanacs. The Jet Propulsion Laboratory in California and the U.S. Naval Observatory in Washington, D.C., have perfected powerful new machine methods for modeling the motions and interactions of bodies within the solar system. At the same time in Paris, the Bureau des Longitudes has been a beehive of activity aimed at describing these motions analytically, in the form of explicit equations.

Yet until now the fruits of this exciting work have remained mostly out of reach of ordinary people. The details have existed mainly on reels of magnetic tape in a form comprehensible only to the largest brains, human or electronic. But Astronomical Algorithms changes all that. With his special knack for computations of all sorts, the author has made the essentials of these modern techniques available to us all.

The second edition contains new chapters about the Jewish and Moslem Calendars, and on the satellites of Saturn, and a new Appendix giving expressions (polynomials) for the heliocentric coordinates of the giant planets Jupiter to Neptune from 1998 to 2025.

Great cooling pillow, and cat-approved!
Color: Purple, Size: Standard, Color: Purple, Size: Standard
I've been using this EGOHOME cooling gel memory foam pillow for a few weeks now, and the cooling feature is definitely the standout for me. The reversible cooling cover really does what it promises — it feels noticeably cool to the touch, especially when the AC is on, and makes a big difference on warmer nights. It helps create that fresh, cool sleep surface that makes it easier to relax and fall asleep. Beyond the cooling comfort, the memory foam strikes a great balance between soft and supportive. It keeps my neck aligned whether I sleep on my side or back, and I’ve been waking up feeling more rested with much less neck stiffness than before. The removable, washable cover is also a practical plus. One small note: the cooling effect does gradually fade after an hour or two without AC, so pairing it with a fan or air conditioning helps maintain that cooler feel longer. And perhaps the highest endorsement I can offer: my cat Duoduo claimed it immediately. She’s been loafing on it with a look of complete ownership ever since — I’d say that’s the ultimate comfort test passed.

Cool, Supportive, and Very Comfortable Pillow
Color: Blue, Size: Standard, Color: Blue, Size: Standard
I really liked this pillow from the first night. It feels soft but still gives very good support to the head and neck, so it feels comfortable in different sleeping positions. I also liked the cooling side, which feels nice especially at night when the room gets warm. The pillow has a good shape, feels well made, and the cover is easy to remove and wash, which is very helpful for regular use. Overall, I feel this pillow is worth buying if you want comfort and support together. It gives a nice balance, not too hard and not too soft, and I woke up feeling more relaxed. The cooling feature, washable cover, and memory foam support make it very practical for everyday use. I am happy with this purchase and would definitely recommend it.

To think and the best cooling
Color: Blue, Size: Standard
The pillow is a little to thin..not as thick as it should be. The cooling feels good for a short period then looses it cooling for me.

Great pillow very comfortable and supportive I was pleasantly surprised by this pillow. It has the perfect balance between softness and support, keeping my neck well aligned throughout the night. The material feels high quality and it doesn’t get too hot, which is a big plus. After a few nights, I noticed better sleep and less neck discomfort. Highly recommend!!!!

Comfortable and stays cool
Color: White-cooling Basic, Size: Queen(Pack of 1)
Great pillow. When i opened it, i noticed a strange smell, i assumed its the smell of whatever they use to make the pillow stay cool. You have to fluff it for a good amount of time to make sure the cooling agent spreads well in the foam. Is what i assumed atleast. Its a perfect amount of softness for me. Pair it with some bamboo pillow cases and you got a good night of sleep
