[:nl]De nationale wetenschapsquiz 2019[:]

[:nl]Hij is er weer, althans..., zoals al heel lang zonder Wim T. Schippers, maar inmiddels ook zonder de NPO, want het schijnt te duur te zijn in tijden van de [hier iets invullen]-crisis. Niet getreurd, voor 13 eurootjes en een even zo duur parkeerticket kun je er bij zijn of je kunt het bekijken op

[:nl]De Nationale Wetenschapsquiz 2018[:]

[:nl]Ze zijn er weer, al even zelfs, maar je kunt nog tot vannacht meedingen naar de prijs/prijzen, de vragen van de Nationale Wetenschapsquiz 2018. Wat zijn jouw ideeën bij de antwoordmogelijkheden? Vraag 1: Je brengt met identieke kristallen glazen een toost uit met champagne en een toost met bubbelloze wijn. De glazen met bubbelloze wijn

De Nationale Wetenschapsquiz 2016

De Nationale Wetenschapsquiz 2015

De vragen zijn er weer, voor de Nationale wetenschapsquiz 2015. Welke antwoorden twijfel jij nog over, of juist niet? Vraag 1 Als je Spa rood in een glas giet waar je net witte wijn uit gedronken hebt, zie je geen bubbels. Hoe komt dat? Antwoord 1: A. Doordat CO2 beter oplost in alcohol dan in

Vraag 1 In de zeventiende eeuw gingen de Britten flessen produceren die de druk van mousserende wijn aankonden. Wat was een belangrijke aanleiding hiervoor? Antwoord: A. Er was te weinig hout om schepen te maken B. Hun ervaring in het

<!--:en-->Beach creatures<!--:--><!--:nl-->Strandbeesten<!--:-->

Deze beesten van kunstenaar Theo Jansen zijn echt een prachtige toepassing van kunstmatige intelligentie. Het toont aan hoe je met relatief simpele elementen toch een enorme complexiteit kan realiseren. De combinatie van GA's (genetische algoritmen) in evolutionary computing en een beginsel van neurale netwerken maken de beesten zelfontwikkelend en intelligent. Zeer inspirerend en ik denk

Nationale Wetenschapsquiz 2009

Hij is er weer, de nationale wetenschapsquiz 2009.   In de Nationale Wetenschapsquiz 2009 neemt een team van wetenschappers het op tegen een team van mensen uit de wereld van de kunsten. Het team van wetenschappers bestaat uit hoogleraar computationele sterrenkunde Simon Portegies Zwart, aquatisch bioloog Marten Scheffer, klinisch psycholoog Sjaan Nederkoorn en hoogleraar insectendiversiteit

Groene innovatie

Weet je wat pas echt handig is? Juist ja, een wasmachine op je WC. Dat is precies wat Sevin Coskun in Turkije heeft bedacht, wel ja eens een keer niet de japanners voor de verandering. Niet alleen bespaard het je ruimte in de badkamer, het is bovendien milieuvriendelijk doordat het waswater wordt herbruikte voor het doorspoelen van het toilet. Bovendien is het makkelijker inladen daar je niet hoeft te bukken om bij de klep te komen, wel moet je je was natuurlijk niet in de toiletpot laten vallen, alhoewel, daar zit natuurlijk ook waswater in.

Intel Robotic Hand

Robotics have come a long way, but they still often miss that innate, nervous sense of reluctant touch. Intel researchers have achieved something similar with a robotic hand that uses electrolocation to create a robotic hand conform to the shape of an object before interacting with it. Shown at Research@Intel Day, the hand uses fish-like

RobotChallenge Vienna 2008

Already more than a month ago, finally I've got the photo's of the RobotChallenge on my web site. The robotchallenge in Vienna is an international event where teams compete in different challenges. Chaekith Chandranna and I participated in the Parallel Slalom and Enhanced Parallalel Slalom challenges. The robotchallenge was a very nice experience. No prizes

Happy Birthday, Mr Feynman

Today, May 11th, it is Richard Feynman's birthday. A great scientist that won the Nobel Prize in Physics. Besides being a great scientist he was able to express the ideas to the general public. The documentary "The pleasure of finding things out" by Horizon is worth the watching and it inspires to do science ;-).
