I thought I’d just add a few photos from a quite nice family hiking trip in Austria this summer. We were in Ramsau am Dachstein. A really lovely area for hiking and relaxing a few days. Some more pictures can be found in the album here.
Det tog sin tid, men till slut kom artikeln ut i alla fall; en artikel i Sensors and Actuators B – Chemical med titeln “Fångst av fluorescerande virus med silvernanotrådar”. Det här är ett arbete som pågått i flera år – artikeln har avvisats, nya mätningar har gjorts, och nu […]
For two days now we have discussed answers to the question You drink a glass of ordinary tap water. How many water molecules in this glass were in the blood of Socrates when he died? First we used probability to determine that the value is at least tens of thousands […]
Yesterday we saw how a normal glass of water contains at least 20000 molecules of water that were in the blood of Socrates when he died. Here, we’ll see why that is completely wrong! You might think it has something to do with the way we estimated the circulation of […]
There is a classic question that comes up every now and then, usually meant to demonstrate how enormous Avogadro’s number is (or alternatively, how damn small a molecule is). There are many versions of it, but the one that I read in Göran Grimvall’s Brainteaser Physics many years ago, goes like […]
Så var det sent omsider dags för nästa uppdatering om mina forskingsartiklar. Den här gången handlar det om en artikel som publicerades av en kollega till mig, där jag bara hade en mycket liten del i arbetet. Det handlar om en artikel om en speciell användning av en teknik som […]
Det har skrivits mycket i dagarna om att forskare lyckats hitta is, inbäddat i diamanter, som “inte troddes existera på jorden”. Det är resultat som presenteras i en artikel i senaste numret av Science där man med hjälp av röntgendiffraktion lyckats hitta kristaller av is-VII (utläses is-sju) inneslutna i diamanter. […]
Electrochemistry might very well be one of the most underappreciated disciplines of science out there. And I’m not saying that (only) because it’s my adopted field and no one seems to have any clue what it’s about. While electrochemistry might not be as sexy as astronomy or as spectacular as particle physics […]
I visited Edinburgh last weekend to try some whisky and meet up with my old PhD-colleagues Martin, Martin and Stina and our old supervisor. Edinburg is a very photogenic city, but there seem to be some pictures that are more or less mandatory – like the one above over the […]
