    Is Golf a Sport?

    By Brett Zarda Posted on 1.2.2009 11 Comments

    It's an age-old question debated in pro shops and pubs across America: is golf a sport? Neil Wolkodoff, director of the Rose Center for Health and Sports Sciences in Denver, thinks it is, and he has some data to back up his claim. Wokodoff took eight better-than-average golfers and tracked their heart rate, oxygen consumption, carbon dioxide production, and how far they were walking through a few rounds.

    If You Dropped a Corn Kernel From Space, Would it Pop During Re-Entry?

    By Stuart Fox Posted on 12.30.2008 14 Comments

    There’s a little bit of water inside each kernel of popcorn, and if you can heat the kernel above 212°F, that water should boil, turn into high-pressure steam, and pop the kernel. But in orbit, things aren’t so simple. First off, the cold vacuum of space would suck all the water out of the kernel before it could pop the corn. So any ordinary kernels would drop, not pop. But let’s say we figured out a way to keep the kernel watertight. In that case, it all depends.

    Unfortunately, the current Administration uses the phrase, "...threat to National security" as a catch-all to quell any public discourse on a vast array of topics. Those covertly supporting totalitarian rule use fear as a weapon -- fear of terrorism, fear of foreigners, fear of civil rights, fear of free speech, etc. Imagining new weapons or new aircraft does not make America less safe. Secrecy and an unchecked federal government is the real threat to our security. evden eve nakliyat evden eve nakliyatevden eve nakliyat evden eve nakliyeevden eve nakliyat nakliyat

    Meet the Navy of the Future

    By Posted on 2.15.2008 1 Comments

    Two year ago, the U.S. Navy embarked on an ambitious 30-year plan to transform its fleet from the current level of approximately 280 ships—the smallest since 1916—into a versatile 313-ship force. The three advanced ship designs you see here would be the Navys main surface-based fighting machines.

    Warships of Tomorrow

    By Posted on 2.15.2008 4 Comments

    Its hard to tell what kind of wars the future will bring, but one thing is certain: Robots will be doing much of the fighting. In fact, they already are. Last year, aerial drones flew 258,502 hours of missions—up from 27,201 in 2002. Spending on unmanned aircraft systems by the U.S. military is expected to hit $3.76 billion by 2010. Robotic warfare, long the stuff of science fiction, is now a reality.

    When they’re not in battle, the UXV’s various drones would be stored on other ships or land bases; when the UXV receives a mission, the relevant drones would be dispatched to it. For a sub-hunting expedition, the UXV might load up with unmanned underwater vehicles, high-tech radars, torpedoes and even manned aircraft like the Super Lynx sub-hunting helicopter. On a mine-sweeping mission, it would deploy aerial drones to peer beneath the waves and destroy hidden threats. To supply ground troops in battle, it would host troop-carrying landing craft, support-attack helicopters and other armored vehicles. evden eve nakliyat evden eve nakliyatevden eve nakliyat evden eve nakliyat

    Green Skies at Mach 5

    By Posted on 1.23.2008 22 Comments

    Modern air travel is a marvel. It's also a source of endless delay, annoyance and planet-killing greenhouse gases. A proposed hydrogen-powered hypersonic airliner could change all that. The plane is Reaction Engines's A2 concept, a Mach-5 (3,400mph) craft for 300 passengers funded in part by the European Union's Long-Term Advanced Propulsion Concepts and Technologies project (Lapcat). Lapcat wants an airliner that can fly from Brussels to Sydney in less than four hours. If built, the A2 will do just that—without producing a trace of carbon emissions.
