New ways of solving problems
Video clip: Stephen Hawking is escorted by KTH President Peter Gudmundson as he arrives for the first day of the Hawking Radiation Conference, being held on the KTH campus this week. Stephen Hawking will present what he describes as “a new idea” concerning black holes tomorrow, at a special conference on Hawking radiation that is … Continue reading “Hawking’s ‘new idea’ about black holes”
What would happen to you if you were sucked into a black hole? Would you disappear without a trace? Physicists have argued for years that these bottomless pits of space-time gobble up anything that gets too close to their gravitational field, seal it away for good, and then eventually evaporate, leaving no trace of what … Continue reading “Hawking and others set out to solve black hole paradox — here in Stockholm”
Your car, home and even your clothes could one day soon be outfitted with soft, squishy and shock-proof batteries that are made from — wait for it — trees. Researchers at KTH’s Wallenberg Wood Science Center (WWSC) used wood-based nanocellulose for this latest breakthrough, which dramatically expands the storage capacity of batteries. “It is possible … Continue reading “Wood you believe? Forests will produce more than lumber and paper”
When we admire great machines, we too often overlook the contribution of the gears. These hardy wheels are unsung heroes of machinery — so undervalued by popular imagination that they inspired the woeful saying: “I’m just a cog in the machine”. But a well-designed gear system can make a huge difference. Take the recent advance in wave energy … Continue reading “What do gearboxes have to do with ocean energy? A lot.”
