What is Physics? [Video]

I spent the holidays watching some tutorials for video animations and learned quite a few new things. The below video collects some exercise projects I did to answer a question Gloria asked the other day: �Was ist Phykik?� (What is phycics?). Embarrassingly, I doubt she learned more from my answer than how to correctly pronounce physics. It�s hard to explain stuff to 6-year olds if you�re used to

How to use an "argument from authority"

I spent the holidays playing with the video animation software. As a side-effect, I produced this little video.

If you'd rather read than listen, here's the complete voiceover:
It has become a popular defense of science deniers to yell �argument from authority� when someone quotes an experts� opinion. Unfortunately, the argument from authority is often used incorrectly.
What is an �argument

I wrote you a song.

I know you�ve all missed my awesome chord progressions and off-tune singing, so I�ve made yet another one of my music videos!




In the attempt to protect you from my own appearance, I recently invested some money into an animation software by name Anime Studio. It has a 350 pages tutorial. Me being myself, I didn�t read it. But I spent the last weekend clicking on any menu item that couldn�t

Wissenschaft auf Abwegen

Ich war am Montag in Regensburg und habe dort einen �ffentlichen Vortrag gegeben zum Thema �Wissenschaft auf Abwegen� f�r eine Reihe unter dem Titel �Was ist Wirklich?� Das ganze ist jetzt auf YouTube. Das Video besteht aus etwa 30 Minuten Vortrag und danach noch eine Stunde Diskussion. Alles in Deutsch. Nur was f�r eche Fans ;)

Is light a wave or a particle?

2015 was the International Year of Light. In May, I came across this video by the Max Planck Society, in which some random people on the street in Munich were asked whether light is a wave or a particle. Most of them answered in German, but here is a rough translation of their replies:
�Uh, physics. It's been a long time. I guess it�s... a particle. � Particle. � Particle. � A particle. � A

Peer Review and its Discontents [slide show]

I have made a slide-show of my Monday talk a the Munin conference and managed to squeeze a one-hour lecture into 23 minutes. Don't expect too much, nothing happens in this video, it's just me mumbling over the slides (no singing either ;)). I was also recorded on Monday, but if you prefer the version with me walking around and talking for 60 minutes you'll have to wait a few days until the

10 things you should know about black holes [video]

Since I had the blue screen up already, I wanted to try out some things to improve my videos. I'm quite happy with this one (finally managed to export it in a reasonable resolution), but I noticed too late I should have paid more attention to the audio. Sorry about that. Next time I'll use an external mic. I have also decided to finally replace the blue screen with a green screen, which I hope
