INTEGRAF--How to Make Holograms "Everything should be made as simple as possible, but not simpler” - Albert Einstein We attempt to follow this dictum so you can make holograms easily. The procedures we propose herein are as simple as it is physically possible. In the process, we make holography not only as simple as possible, but safer, less expensive, and more accessible to young people. Most of the essential items described in this article can be found in Integraf's holography kits or are available separately. The kits provide materials for you to make many kinds of holograms, including reflection holograms and transmission holograms. The figure below shows a Class IIIa diode laser with an output of 3 to 4 mW when operated by 3.0 v dc. An excellent support for such a small laser is a wooden clothespin, as shown below.

Presently, instead of subjecting people to cons, Mr Lovell stars in a one-man off-Broadway show, "Strange and Unusual Hobbies".

But he still had his boat shoes, his Darwin-esque beard, and an eagerness to demonstrate his sail-handling skills while discussing his 16th book, “Intuition Pumps and Other Tools for Thinking,” which W. W. Never mind that the boathouse’s fleet was unexpectedly confined to shore, thanks to a temporary shutdown of river traffic. Sailing was still an apt illustration of the kind of empirically minded problem-solving that Mr. “Philosophers can seldom put their knowledge to practical use,” Mr. These days, Mr. But for decades, he has presented himself among his fellow philosophers as a ruthless slayer of metaphysical fancy.
