That's what I'm getting at: Ad hominem seems to be the only go-to rebuttal, and as we all know that's a logical fallacy and isn't a rebuttal at all, much less a counterargument.

I wish that ocean acidification was brought up more often in the context of the climate change discussion. People can attempt to deny that CO2 warms the planet, or that said warming is a bad thing, but you cannot argue with the basic chemistry that carbon dioxide dissolves in water as carbonic acid, and acidifies the

take another look, it's .44% , or less than half a percent the speed of light. Very fast, but nothing like .5c .

Æthelwulf and Æthelred are about as far back as I've been able to trace my ancestry. Interesting to see Æthelred mentioned on io9!

Add nuclear baseload power to that list and you have an excellent argument!

It's too late to edit my earlier post, but it turns out that I didn't hear about the connection between Salem and ergotism in a work of fiction (or, if I did, it was well-informed fiction!); the wikipedia article on ergotism has a whole section about the Salem witchcraft accusations: https://en.wikipedia.org/wiki/Ergot

The Pointe-Saint-Esprit mass hysteria was not caused by LSD, at least not unless you buy the CIA conspiracy theory. Ergot, a mold that contains compounds that are similar to LSD (and can have somewhat similar effects), has been implicated - moldy bread, essentially. Still others think it may have been mercury

Spaceship Two isn't designed for orbital flight at all. It's all completely suborbital. Up to 62 miles and then back down. There's no associated necessary velocity in this case, since they aren't trying to attain orbital velocity, just technically reach "space" by attaining an altitude above the Karman line for a

An article like this really makes me wonder about the Skyscraper Index.

Should I be worried?

Humanity ought to have an insurance policy to avoid extinction. Self-sustaining colonies on Mars are the way to go.

There's a new Commonwealth book coming out on October 21st - "The Abyss Beyond Dreams" - and that got me to reread Pandora's Star and Judas Unchained. I ended up spending an entire Sunday plowing through Judas Unchained; the second time was better than the first! I'm considering re-reading the "Void" books too, but

Point 1 is important because, at least in the near future, any space habitats are going to be dependent on raw materials from back on Earth (fresh water, food, replacement parts); also if there's global ecological collapse/unrest/famine/the like, how will governments be able to justify spending on space with so many

Michael Jackson - Dangerous. It's the first I remember asking my parents to buy for me when we were at the mall when I was 6 or 7.

I already had access to my dad's collection of The Doors and The Beatles and Creedence and The Moody Blues (et cetera - you get the idea) , but Dangerous was the first CD that was mine,

I found it confusing as this is a two-fold treatment involving gold nanoparticles and cisplatin, a chemotherapy drug. Cisplatin doesn't cross the blood-brain barrier. Nitrosureas can, but cisplatin - like other metal salts (carboplatin, oxaliplatin) - cannot. I thought maybe they could be looking at infusing the

When you see a claim that [insert cool-sounding new treatment here] kills cancer cells [in vitro], keep in mind: So does a handgun.

And how are they going to get this stuff through the blood-brain barrier? Sorry to be a buzzkill, but glioblastoma has really earned its awful reputation; do not pass

People who use the word "libtard" immediately prove themselves to be so unoriginal as to warrant completely ignoring anything else they may say. Just a friendly tip if you want people to take you seriously in the future.
