Homebrew CPU Engineering ToolBox Elementary Calculus This is a calculus textbook at the college Freshman level based on Abraham Robinson's infinitesimals, which date from 1960. Robinson's modern infinitesimal approach puts the intuitive ideas of the founders of the calculus on a mathematically sound footing, and is easier for beginners to understand than the more common approach via limits. The First Edition of this book was published in 1976, and a revised Second Edition was published in 1986, both by Prindle, Weber & Schmidt. The book is now out of print and the copyright has been returned to me as the author. This work is licensed under a Creative Commons Attribution-NonCommercial-ShareAlike 3.0 Unported License.

Best Classic Books to Read Reading classic books can boost your learning experience. There are some reasons why classic books can do that: they have stood the test of time, they give you different “lenses” to look through, and they will most likely be relevant even to the far future. Reading the classics is an excellent intellectual exercise which will arm you with a lot of powerful intellectual tools. To find good classic books, there are trusted recommendations that can help us. While I believe a book which is recommended by any of them is good, I think it’s safe to say that a book which is recommended by both of them is great. So without further ado, here are the recommended classic books along with the Amazon and free download links (if any): Novel Autobiography and Memoir History Drama Poet It may take years to read all these books, but it undoubtedly will be a very rewarding intellectual journey; they are among the best books of human civilization.

Simple mechanisms explained Email Below you’ll find animated diagrams and explanations of how various mechanisms work. Some of these have been crucial to major evolutions in mechanisms and technology, and allow us to do anything from fire weaponry to make cars move with the press of a pedal. Maltese Cross mechanism powers second hand movement in the clock: Radial engines are used in aircraft. Reciprocating movements power steam engines in locomotives: Sewing machine: Manual transmission mechanism, also known as “stick shift” is used to change gears in vehicles: This mechanism is called constant-velocity joint and is used in front-wheel drive vehicles: Torpedo-boat destroyer system is used to destroy fleet in naval military operations: The Wankel engine is a type of internal combustion engine which uses a rotary design to convert pressure into a rotating motion instead of using reciprocating pistons: + Bonus – mechanism you can watch forever Leave your comment: You may also like these posts:
Shroomery - Magic Mushrooms: Which mushrooms grow wild in my area? Panaeolus subbalteatus (know as subbs by some people) is by far the most widely distributed psychoactive mushroom in the United States (if not the world). Although this mushroom is typically ranked as "weakly potent" to "moderately potent," it's all that some people will be able to find. This guide contains a very large amount of pictures of Panaeolus subbalteatus and it's most common, inactive, look-a-like Panaeolina foenisecii. First I will start off by explaining the best places and times of year to find these mushrooms. Habitat. P. subbalteatus grow in many natural environments. Season and when to hunt. Look-a-likes / Description These mushrooms (subbs) tend to be a bit difficult to identify because there are many member of the Panaeolus and Panaeolina genera which look very similar to them. The easiest being the stem. Here are some pictures to illustrate some of the things I just discussed: Left to right these arrows point out the following (Photo by: Gumby) 1. Picture Galleries:
Free video lectures,Free Animations, Free Lecture Notes, Free Online Tests, Free Lecture Presentations Online Book Club for Readers First of all, this is not some crazy online get-rich-quick scheme. You won't get rich and you won't be able to leave your day job. This also isn't one of those things where we promise you billions of dollars if you just send us a small fee. So what is this? Many publishers and up-and-coming authors are willing to give you a free copy of their book in exchange for you writing an honest review of the book. In fact, there is such a high demand for reviewers to accept these offers that many of them are now coming with a payment in addition to the free book. Most payouts currently range between $5-$60 per review. If you are the kind of person who hasn't read a book in the last year, this probably isn't for you. To get started, just sign up for free by registering if you have not already. Click here to sign up for free now! Why do authors/publishers want these honest reviews so much that they are willing to give away free copies of their book and even pay money? What if the review isn't good?
Free Plans-Model Steam Engine A curriculum support site providing free lab-project plans for technical students, their teachers and others interested in applied mechanical engineering. SPECIAL NOTE: Tripod generously provides this web space free: unfortunately, they do not provide unlimited bandwidth. This site has been fairly popular and as a result, it has occasionally overused the free bandwidth provided. If you have trouble re-reaching this site, wait a few hours and try again! Brought to you by County College of Morris Engineering Tech Department, Randolph, N.J. My country: Land of the free.....Home of the brave..... These pages are designed to provide plans, ideas and inspiration to would-be steam engine enthusiasts. Who might use some of these ideas and plans? Why would anyone be interested in the steam engine? Note that some of the pages provide pictures, construction notes and actual plans while other pages provide only pictures and construction notes. Why have we created this site? 1. 2. 3.
