I am a geek in that I have a strong interest in science and technology (amongst other things). I am proud of the achievements of science and I thing science should be promoted and encouraged, especially amongst young people but also across the population in general.
Living in a country where the radio and TV are in a language I don't speak very well has forced me to seek other forms of mental stimulation for my drive to work and while sitting at home. I recently discovered podcasts which are a great way of getting something worth listening to onto your ipod/iphone.
If you are interested in science I suggest Radiolab, its a totally awesome science show. They have this unique style which takes a little getting used to, but when you do you will be hooked. Gareth first pointed me towards it and I was a bit sceptical at first. Now I love it. They do 1 hour podcasts of their regular radio shop and also special "shorts" which last about 15 mins and are perfect for my drive to work. I really can't recommend this show enough. I love it. Check out http://www.radiolab.%20orgb/ or go to itunes and seach on radiolab and download and enjoy.
Science weekly from the Guardian - another very good science show, worth listening to
If you want some history, A History of the World in a Hundred Objects is a great series of podcast shorts about history told though objects by the director of the British Mueseum. Again a perfect length for my drive to work and highly educational.
Finally if you want some politcis and current affairs the Young Turks offers an educated, informed and opinionated liberal view on American Politics. It is a fantatsic antidote to the idiots like Rush Limbaugh
To download a podcast, simply go to the very shit piece of software that is iTunes and search for your chosen cast. All the ones above are free so when you find them, follow the instructions download, listen and enjoy
