Pale Blue Dot (video)

Pale Blue Dot

No introduction or commentary on this one. This is a segment from my planetarium show (the Earth segment) rendered for smaller screens, so the quality may be reduced a bit. The quote is from Carl Sagan's book, Pale Blue Dot, an amazing read which I would suggest all audiences to give a look at. There is no intro music to this, but music throughout and is done by Yo-Yo Ma, called the Ecstasy of Gold, from his album where he plays a bunch of music from Ennio Morricone's compositions.

Many of the images have been used without acknowledgment of the authors from If your image was used, please let me know and I'll credit you.

Galileo's Thread

Galileo's Thread

It is a common misconception to think that things that weigh more than others fall faster. After all, we see all the time that paper floats to the ground when our cellphones drop quickly onto the pavement. Galileo, in the 1600s, disproved this with a simple string.

Lucretius' Spear

Lucretius' Spear

Are the boundaries to the universe finite? If so, what exists beyond them? Lucretius wondered this in his work, On the Nature of Things. If the universe is infinite, how do we fit in? This podcast aims at explaining that.

Euthyphro's Dilema

Euthyphro's Dilema
(music by Harry-Gregson Williams)

Hopefully this will synchronize to the old podcast feed. Some updates to note of are a planetarium show preview I will be hosting in video format in a few weeks and a skypecast in a couple months from now. Andrew is gone but slated to return in a few weeks from a brief "vacation".

This podcast details where morality is derived from: objective or subjective sources?

First new podcast

What Is a Thought Experiment?

The new podcast is kicked off. The future of the show will detail the history of thought experiments, ones from the fields of physics, math and philosophy, too. Expect controversial topics like religion and things like that to come!

For those arriving from Thought Provoking Discussion, welcome and yes, we are continuing the plan from the other blog message.
