January in quantum physics

The beginning of the year was filled with great physics. Lots of interesting theory has been done, including by me (but more details on that later). But today I want to talk about three experiments that push our abilities to control matter using light into new regimes. In two of them, scientists were able to observe quantum effects in the motion of levitated objects for the first time. In the third one, the authors used their incredible control of single atoms to create a very thin and light mirror.

Academia, Personal

Scientific presentations and the art of storytelling

How many talks have you attended in the last year? And how many of those did you enjoy? Even when the topic itself is interesting, one often leaves disappointed. Some speakers spend too much time on technical details and do not have time to discuss the main results; others are not well prepared and keep… Continue reading Scientific presentations and the art of storytelling

Benefits and challenges of tweeting a conference

Academic conferences are usually exhausting. You spend the whole day (or, more often, several days) closed in a lecture room, often without direct sunlight or fresh air, and try to absorb as much information as you can from (sometimes poorly prepared) talks of your fellow researchers. At some events, speakers change as often as every 15… Continue reading Benefits and challenges of tweeting a conference

Is the Moon in the sky when you’re not looking?

If you find quantum physics hard to understand (or accept), rest assured that you are not alone. Even many physicists (including Albert Einstein, one of its founding fathers) refused to acknowledge that our world can behave so strangely. That atoms or electrons can be at two places at once or that it does not always… Continue reading Is the Moon in the sky when you’re not looking?
