editorial Mado Martinez There was a man who wanted to stop Editorial Director time. So deep was his love for the idea that he actually did it. We refer to Dr. Ispectrum Harold Edgerton, the inventor of the strobe flash. Through his photography, he magazine stopped time in its tracks and for the first time we were able to see the wonderful Published Bimonthly ISSN 2053-1869 details that escape human eyes. There is no one better then, than Gus Kayafas, Editorial Director Edgerton’s longtime assistant and editor, Mado Martinez, to provide an article about him. For those [email protected] who are in London, I suggest you to visit the exhibition at Michael Hoppen Gallery Art Director about his work. Rayna Petrova [email protected] Our second topic is going to challenge the way that we think about height. We Contributing Editors have always been told that taller people Matt Loveday have many social advantages. Maybe this [email protected] is true, but Thomas T. Samaras, author of The Truth About Your Height, shows us Jennifer James that taller height can have a dangerous trend… Charlotte Shelton I have an important question to put to Contributing Writers you before continuing with the summary Gus Kayafas of this issue. Do you care about first impressions? Do you know how much Thomas T. Samaras a first impression can influence you as an individual, or even an entire society? Rob Hutchinson With Rob Hutchinson, our expert in psy- chology, you are going to learn what the Mark Miller halo effect is and how it works. Images Finally, there is a matter of discussion www.commons.wikimeadia.org , that we should be worried about:Will the www.morguefile.com , websites and the electronic documents www.freeimages.com that we use today last forever?

Dr. Harold EdgertonThe man who stopped timeabstractions P hotography has illumi-by nated so many areasGUS KAYAFAS of the 20th century, but none more so than the remark- able work by one of photog- raphy’s true pioneers. As an Institute Professor at MIT, and the inventor of the ‘strobe’ flash in the early 1930s, ‘Doc’, as he was affectionately known, stopped time in its tracks. For the first time we were able to see the wonderful arc of the tennis racket or a bullet break- ing a sheet of glass and, of course, a milk drop splash at the moment of impact. 3

For example, a 10% tons.increase in height increases weightby 33%. Surface area does notincrease as fast as weight e.g. sur-face area would increase by 21%.The reason for the disproportion-ately larger increase in body weightwith height is due to the fact thatwhen we get taller, we also getwider and thicker. As a result, apopulation averaging 10% taller,increases demands on our annualfood, water and energy needs by33%. For example, if a populationof 300 million Americans increasedby 10%, we would require 50 mil-lion more tons of food, 30 trilliongallons of water, and 16 quadril-lion BTUs (BTU-the amount of heatenergy needed to raise the temper-ature of one pound of water by onedegree F) of energy.

Our diet and lifestyle have already created hugeexpenses in this area and increasedheight will increase them further.When all these factors are com-bined they would require an annualUS expenditure of about $1 trillionUS dollars. As can be seen, increasing bodysize is not free. If taller, heavierpeople were much more creativeor productive, bigger size mightbe justified.

Some admirers in person, theyof the world’s greatest achievers often hear:have been shorter than averageas illustrated next. “I thought you would be taller.” When famous shorter peoplemeet their admirers in person,they often hear: “I thought youwould be taller.” This assumptionis unwarranted because the world’shistory is full of famous shorterpeople. Let’s take a look at some ofthem who range from less than 152to 170 centimeters.In the case of business success, Michael Bloomberg, former mayor of NewYork City is on the short side. Others include Andrew Carnegie, AristotleOnassis, Armand Hammer, Ross Perot, Herbert Haft, and David Murdock.Famous short leaders include Churchill, Gandhi, Martin Luther King, PresidentMadison, Alexander the Great, Ben-Gurion, Joan of Arc, Vietnamese GeneralGiap, Admiral Nelson, Prince Eugene of Austria, and General Krulak. 21

In music, Mozart, Mahler, Beethoven and Stravinsky were on the short side.If we look at artists, we find Picasso, Juan Miro, Thomas Benton (US),Salvador Dali, and Michelangelo.In the movies, Tom Cruise, Al Pacino, Anthony Hopkins, Dustin Hoffman, andRichard Dreyfus are well-known shorter actors.Great athletes include Tara Lipinski, Maradona, Pele, Jorge Campos, ScottHamilton, Bruce Lee, Jet Li, Olga Korbut, and Suleymanoglu.Famous scientists include: Millikan, Michelson, McClintock, Einstein, Steinmetz,and Buckminster Fuller.Great writers include John Keats, Alexander Pope, Voltaire, Jean Paul Sartre,Tennessee Williams, William Faulkner, and Upton Sinclair. 22
