Dr. Karl has wide-ranging knowledge in multiple fields of science and the honestly to say when he doesn’t know the answer to a question. Thanks to Dr. Karl and all those involved for entertaining and enlightening so many people.

There are lots of science shows and podcasts but Dr. Karl has the best one. He is great at explaining complex concepts and is funny and kind to listeners. He has a great positive attitude. I have learned lots of interesting things from his question and answer programs and they are thoroughly entertaining. Look for his other ones including regular appearances on the BBC 5 Live Science Podcast and his website too!
