The New Press is pleased to announce the publication of this new title with the American Museum of Natural History, a collaboration that began with the publication of Epidemic! in 2000.
Founded in 1869, the American Museum of Natural History in New York City is one of the world's preeminent institutions for scientific research and education, visited by more than four million people annually. Three new titles, Earth, The Biodiversity Crisis, and Cosmic Horizons, are companion volumes to three major new permanent exhibitions at the museum: the David S. and Ruth L. Gottesman Hall of Planet Earth, the Hall of Biodiversity, and the Frederick Phineas and Sandra Priest Rose Center for Earth and Space.
This introduction is an all-encompassing look at the Earth: how it was formed and how it works. It explores the emerging geological research and explains how new advances in the understanding of plate tectonics, seismology, and satellite imagery have enabled us to begin to see the Earth for what it is, a dynamic and ever changing planet. It introduces the concepts of plate tectonics, continental drift, the earth's structure, and sea-floor spreading.
Our review: "When I came across this little book for the first time in Bookshop Santa Cruz I almost paid full retail for it! I did go straight to the shop and order a bunch of copies. I'm not disappointed. Earth : A Very Short Introduction has become an instant favorite and one of my must have recommendations. Here's a little pocket size book that you can carry with you just about anywhere. It has great coverage of the principles of geology and is presented in a narrative style. This is a fun read, not a dry geological text."
The BelOMO 15x Triplet Loupe magnifier has a viewing area of 0.38in (9mm). The 3 elements making up this achromatic triplet provide a bright and clear view. The 15x power magnification provides a nice level of magnification, good depth of field (the area that appears in focus on an object having an irregular surface like a rock or mineral). The lens glass isn't as large, wide, as the famous BelOMO 10x Triplet Loupe Magnifier but there's still lots of light for a very bright view when you need or want just more magnification than the BelOMO 10x Triplet Loupe Magnifier but not as much magnification as the BelOMO 20x Quadruplet Magnifier.
The housing and cover are coated with a matte black finish and assembled using flathead screws. Screws allow you to adjust the swing tension to your liking. Belarusian Optical and Mechanical Association (BelOMA), makers of sights for guided weaponry, camera lenses, and other optical components manufacturers these loupes.
We highly recommend this loupe! The BelOMO loupes are the loupes we always use though it's the 10x that we typically carry in the field. The 15x has a more magnification with a good field of view. But the magnification is just too much for the field so it's the BelOMO 10x Triplet Loupe Magnifier carry.
Don't let this price fool you. The BelOMO loupe is a FANTASTIC buy. These are quality lenses that stand on their own against the higher priced competition. Take advantage of the recovering Belarus economy and a military supplier finding other revenue streams in a capitalistic market.
Each BelOMO loupe we ship is custom treated to prevent the screws from coming loose with usage.
This is Estwing's newest geological tool and sure to become the standard the rock pick carried by geologist and rockhounds.
The main differences between the hammer (Big Face) and the Estwing Supreme 22oz Pointed Tip Rock Hammer is the new Big Face has, wait for it, a bigger face. Think of it like a bull dog or a pug. It's like the 22oz hammer's striking edge is "pushed in" towards the shaft. Like a mountain range created when two plates collide! Or like that day you spent hours pounding away on a chisel. The 22oz hammer's head is about 7/8'' square while the Big Face hammer's head is 1 1/8'' square, about a 1/4'' bigger on each side. Speaking of chisels, this rock hammer's head makes it much better for driving chisels.
Overall the weight of the Estwing Supreme Big Face 24 oz Pointed Tip Rock Hammer E6-24PC and the Estwing Supreme 22oz Pointed Tip Rock Hammer E3-22P are about the same. The Big Face has extra head weight which imparts a more powerful impact, but the overall weight was held the same by attaching the grip to the handle shaft in a different way. (see the images below)
Light enough to easily carry but heavy enough to crack some rock. Estwing Supreme quality in a one-piece forged pointed tip rock pick. Fully polished solid steel with the Estwing shock absorbing nylon-vinyl grip which has been tested to reduce shock by 50%.
