To define a function: f = (x,y) -> x^2 + y^2 To evaluate: show f(3,4). If you exclude the arguments: show f you get: *function (x, y) { return add(pow(x, 2), pow(y, 2)); }*. That's really cool.* *Provides a great way to discuss functions both mathematically and computationally.

BLUE ANGELS vs. BEARCATS Here's a little bit of Naval Aviation history in the making to share as we all celebrate 100 years. Gotta love the sound of the R-2800! The old vs. the new .... what a neat story and so well done... The Blue Angels have always been my all time favorites... These pilots have flying in their blood and it shows here. The 90 year old ex pilot......he's still at it and enjoying every moment even though he no longer flies these planes ... he is flying again thru the others.....and loving every second of it. The Bearcat has a max. speed of 455 mph The F-18 has a max. speed of 1,190 mph The Bearcat has a climb-rate of 6,370 ft/min The F-18 has a climb-rate of 50,000 ft/min The bearcat has a nominal weight of 8m pounds The F-18 has a nominal weight of 23m pounds

scenes of F-104 seat ejection; drop tests from C-130 and ejection from F-106; effects of weightlessness on cats and pigeons in a C-131; test subjects in water tank, on centrifuge, in heat chamber and on complex coordinator. Also shows scenes of vertical deceleration tower, incline impact test facility, vertical accelerator, equilibrium chair and vibration platform.

Those memories begin in 1966, and long lines of interesting aircraft spring to mind. "Monthan" is Davis-Monthan Air Force base at Tucson, Arizona. Home of AMARC * or MASDC * as it was known when I first "scouted" it out, travelling there all the way from Scotland. As a schoolboy, I had seen a few photographs of a "Boneyard" in Arizona. They showed stacks of Republic F-84F and F-84G Thunderjets piled four high, that captivated me, it still does. I have made several trips to Tucson and hope to visit a few more times. In this section I will be adding photos and slides taken during these visits, mostly in 1968, when I spent two days walking the base with my good friend Tom Baillie.

These are the latest sea trials of the F-35B on the USS Wasp. They were very successful, with 74 VL's and STO's in a three week period.

"The Navy has released video of the April 11 one-engine landing made by an F/A-18C aboard the USS Carl Vinson and during which the aircraft caught fire. ... Flight deck fire crews responded and the fire was extinguished with aqueous film forming foam. ... its pilot escaped the episode uninjured."

"Introductory Physics I with Laboratory Michael F. Schatz Explore motion in the real world using modern tools and techniques (video capture and analysis, computer modeling) guided by fundamental physics principles."

"G.F.C Rogers, in his book "The Nature of Engineering" (1983) defines engineering as "the practice of organising the design and construction of any artifice which transforms the physical world around us to meet some recognised need.""

"Discovery of Elements 113 and 115 - Two superheavy elements, elements 113 and 115, were recently synthesized through a collaborative effort between scientists from the Physical and Life Sciences Directorate at the Lawrence Livermore National Laboratory and researchers from the Joint Institute for Nuclear Research at the Flerov Laboratory for Nuclear Reactions in Dubna, Russia. Two isotopes of element 115 survived 30-80 milliseconds before decaying into isotopes of element 113 that survived approximately ten times longer prior to decaying themselves. F"

"The mission of Stennis and her embarked Air Wing (CVW-9) is to conduct sustained combat air operations while forward deployed in the global arena. The embarked Air Wing consists of eight to nine squadrons. Attached aircraft are Navy and Marine F/A-18 Hornet, EA-6B Prowler, MH-60R, MH-60S, and E-2C Hawkeye. The Air Wing can engage enemy aircraft, submarines, and land targets, or lay mines hundreds of miles from the ship. Stennis's aircraft are used to conduct strikes, support land battles, protect the Battle Group or other friendly shipping, and implement a sea or air blockade. "

"neurons came in such a beautiful diversity of shapes. Each of these neurons has a different function, too: A. Purkinje cell B. Granule cell C. Motor neuron D. Tripolar neuron E. Pyramidal Cell F. Chandelier cell G. Spindle neuron H. Stellate cell."

"The F-4 Phantom II was an awesome jet for its time, and still impresses 50 years after its introduction! Hard to imagine, but the jet first entered service in 1960 with the U.S. Navy. Its claim to fame include being used by both the Blue Angels and Thunderbirds as their demonstration aircraft (albeit for just a few years due to the high costs associated with running it), and the top dog fighter-bomber in the Vietnam war.

"New York to London SR-71 Speed Run - On September 1, 1974 Major James V. Sullivan, 37 (pilot) and Noel F. Widdifield, 33 (reconnaissance systems officer) (photo inset), flashed across the starting line (radar gates in New York) at approximately 80,000 feet and speed in excess of 2,000 miles per hour. Exactly 1 hour 54 minutes and 56.4 seconds later, they had set a new world speed record from New York to London England. The average speed was 1,807 statute mph over the 3,461 statute mile course, slowing to refuel one time from a specially modified KC-135 refueling tanker. "

"Personal observations on the reliability of the Shuttle by R. P. Feynman Introduction It appears that there are enormous differences of opinion as to the probability of a failure with loss of vehicle and of human life. The estimates range from roughly 1 in 100 to 1 in 100,000. The higher figures come from the working engineers, and the very low figures from management. What are the causes and consequences of this lack of agreement? Since 1 part in 100,000 would imply that one could put a Shuttle up each day for 300 years expecting to lose only one, we could properly ask "What is the cause of management's fantastic faith in the machinery?""

The National Science Foundation, for example, is embracing the formula to try to increase commercialization of the university research it finances. Last fall, the foundation announced the first of a series of grants for what it calls the N.S.F. Innovation Corps. The 21 three-member teams received a crash course at Stanford in lean start-up techniques, and have been given $50,000 each and six months to test whether their inventions are marketable.

Imagine sitting in your living room when suddenly you find yourself in the Presidential Gallery of the National Museum of the U.S. Air Force, standing on the steps of the Sacred Cow, the aircraft on which President Harry Truman signed the National Security Act of 1947 creating the U.S. Air Force. Glancing around you also see John F. Kennedy's Air Force One, the same aircraft used to bring his body back to Washington D.C. in 1963.

the Navy successfully got an F/A-18E Super Hornet airborne using its new-model catapult, the Electromagnetic Aviation Launch System, or EMALS. not only is the new launch system supposed to be more efficient than steam, it's better capable to launch small drones as well as big planes, giving aircraft carriers a broader range of options.
