"The Hitchhiker's Guide to Ebola"

Don't panic is the message.

Ebola is a scary disease, made much more scary by some wildly exaggerated claims in some books and movies. So, before we talk about Ebola, let's talk about another scary disease called "rabies."

It's a virus, serum transmitted -- meaning contact with blood, saliva, or other bodily fluids from an infected individual is needed to transmit the disease. Thousands of people die of it worldwide, every year. Once you've sickened with it, become symptomatic, the symptoms are pretty horrible, and there's really no effective treatment. People who develop the symptoms are very likely to die.

In fact, the number of people who have survived active rabies can be counted on one hand with fingers left over.


"The Universe"

I can't decide which is more remarkable: the story of the Big Bang told here or that humans, on our one puny little rock in space, seem to have figured out so much about that story.

Some possible problems with the story: "Cosmic Inflation Theory Faces Challenges" and "The Big Bang is not the beginning of our universe — it’s actually the end of something else entirely".

A rebuttal: "What If Cosmic Inflation Is Wrong?".
