An unexpected surge in global atmospheric methane is threatening to erase the anticipated gains of the Paris Climate Agreement. This past April NOAA posted preliminary data documenting an historic leap in the global level of atmospheric methane in 2018, underscoring a recent wave of science and data reporting that previously stable global methane levels have unexpectedly surged in recent years.

The scientific community recently responded to the surge into two high profile publications by calling for a reduction in methane emissions from the natural gas system…

It is not clear where this methane is coming from, but most bets are on wetlands that have shifted from being greenhouse gas sinks (or neutral) to being greenhouse gas emitters. Methane is a bad greenhouse gas while it lasts (decades) but eventually changes into CO2 and water. The CO2, of course, stays in the atmosphere for much much longer. So, this is really like CO2 release but with a giant kick in the gut right out of the gate.

To calculate the exact location of a star, planet, or satellite, read the appropriate chapter in this book, download the source code, data files, or binaries, as needed from the publisher, and off you go on a wild adventure that combines star gazing, mathematics, and coding.

I am especially attracted to science or technology books that contain something the reader can work with. A book about a programming language should walk the reader through developing a good example of useful code. A book about computational science should include templates for workflow in data analysis. It is rare, though, to find a book about a pure science (as opposed to technology) that does this. A 957530CM A 957530CM Kennel Dog Bed Dog Box pet Bed Pet House Cat nest delivery Room Pet Supplies Indoor and Outdoor Solid Wood (color A, Size 95 75 30CM) by J. L. Lawrence is one of those pragmatic publications.

J.L. Lawrence comes from the world of technology. He is a CTO of a company that builds computer systems for satellite-launching customers including the government. So, one might imagine that he has an interest in pulling out the old slide rule and doing applied rocket science.

Consider the situation of a serious amateur astronomer. You can look at the stars and planets through a good set of binoculars, or an amateur telescope. After a while, you may want to upgrade to a telescope that can be linked to your laptop for positioning. Or you might build Grey 34 cm Grey 34 cm Beeztees Joggy Dog T-Shirt, 34 cm, Grey to allow your camera to get a nice shot of a comet. And so on.

But eventually you may also want to get into the math of the heavens, combining that with some coding skills you can easily pick up, and figure out how to locate planets, find specific stars, track the moon’s behavior with great accuracy, and convert between all the values of time and space that happen when round objects of various sizes find themselves falling towards each other in great, seemingly infinite time, spirals. And so on.

Celestial Calculations is written for amateur astronomers who want to use accessible math combined with extensive ready to go code written manly in python, java, and visual basic.

The prose that discusses the math and astronomy is straightforward and accessible, and if you read the book just for that you will come away much better informed about the solar system and broader universe. If you do that, you will probably skip about 20% of the technical discussions and math (maybe a bit more). The math is very clear and you can work through the concepts in your head, more or less, to get the idea, and appreciate the dynamic relationships between things in space. The programming is all relegated (but with notes in the book) to a major on line archive that you can download and use on your own computer to make the calculations, and modify as you wish.

The software is developed with a Microsoft Windows user in mind. The software should run on any platform, but you may have to fiddle with paths and other environment issues if you are using a non-Windows machine.

Ninety-seven percent of North Atlantic cyclones form after June 1st and before November 30th. Note that the end of the Atlantic hurricane season used to be October 31st, but it was moved because the hurricane scientist got tired of cleaning out their locker six times a year instead of just one time. Over the many years of tracking storms, 89 named storms have happened outside the named season.

So it is not utterly odd that Tropical Storm Andrea is now swirling about in the Atlantic, southwest of Bermuda.

It is possible, but unlikely, that Andrea will turn into a hurricane. It is too early to be sure bla bla bla but all the available information about this storm strongly indicates that it will move up the middle of the Atlantic and eventually become a large wet spot somewhere in Europe. I’m putting my money on Ireland. (yes, I now, too early bla bla bla, but Ireland.)

For your information, the next named storm will be Barry. Then…
