Good science a la Hal Clement, 1950s sci-fi

As readers of my blog would know, I am taking an Intro to Biology class via EdX.org and MIT. It is free, and for self-improvement and education (or job-readiness) rather than course credit.

Lately, they have been discussing evolution (a concept I actually agree with) as demonstrated by shared elements of mammalian genomes (human and chimp and lemur and mouse, for instance). It really bothers me that the scientists seem so inperturbably self-assured over the origins of life, which I hope is even a more powerful comment seeing that I respect and agree with their theories. Where is the healthy skepticism?

I was reminded recently of the author Hal Clement and his excellent books (such as Half Life) and short stories (such as "Proof"). I did think a lot of his higher acclaimed books, such as Mission of Gravity, but they made less of an impression on me.

I found this link reviewing Half Life: http://www.sfsite.com/09b/half65.htm

"Clement's references aren't all scientific, and some of them will be quite amusing to Golden Age SF fans. A lot of space is given over to General Order 6 -- an attempt to avoid hastily jumping to conclusions by requiring anyone with a hypothesis to present at least one viable alternative. This is also referred to as the "Aaron Munro instant-certainty syndrome," in reference to John W. Campbell's famous character of the same name."

Here's review of the author:

I also found this quote for Hal Clement online: (I'm shocked this is all I can find)
"Speculation is perfectly all right, but if you stay there you've only founded a superstition. If you test it, you've started a science."

I need to read his 1993 novel Fossil and his 1950s award-winning short "Uncommon Sense"

Turok's Fate: Deathmate

I'm finding out more things about Turok's days with Valiant Comics.
Actually, I am learning more about the comic book industry in general, Valiant in particular, and Turok as a desired consequence.

Apparently, there was a "comic book speculator boom of the 1990s" hyperbolicly termed an apocalyse of sorts of which Turok (through Valiant Comics) was a part. Back then, Valiant proudly touted it as "the Valiant Era."

I need to go now, but I wanted to put up these links:


http://badmouth.net/the-comic-book-apocalypse/ (this is GOOD stuff)
The Image Story: Part 3 of 4, critiquing the Image side of Deathmate
also failed at finding it on Google...lost to the ether, I guess.

worth a read? dunno yet: http://www.oocities.org/valiantfanfic/magvsaliens1.htm

Hey, this guy wasn't in Jurassic Park: Carnotaurus



From my reading, I am given to understand that Carnotaurus (Meat-eating bull-lizard) was roughly contemporary with Tyrannosaurus Rex and Allosaurus, and of similar contour, but was off doing his own thing on the then-island of South America, which much like the Australia of then and now, was an isolated continent giving rise to unique forms.

Actually, also from my own reading, I recall many other examples of the peculiarity of South American fauna, represented even today by the sloths and their xenarthan brethren. You see, South America didn't connect up to North America directly until about the last Ice Age.

Apparently, I am just now learning something many 4-year-olds probably know. There is apparently a year 2000 Disney animated movie that features Carnotaurs fairly heavily. Gonna have to see that sometime.


I am wondering if that's the dinosaur on the Turok animated movie cover.
There is so much genetic and evolutionary hanky-panky in Turok's Lost Land that I don't think it matters much.
