More prescient than even he would have expected

November 19, 2013

demonhauntedIt is well-known that Dr. Sagan was not religious – he described himself as agnostic, believing he had seen no proof of a supreme being. His 1995 book, The Demon Haunted World, was about using the scientific method and critical thinking instead of superstition and pseudoscience.

Admirable goals, and Carl Sagan was very articulate. His Cosmos series and book (PBS, 1980) probably did more to to help laymen understand the universe than any previous media program. (He also wrote the novel upon which the Jodie Foster film Contact was based.)

But I doubt he would have expected that his description of America in the quote above would have happened so quickly, or that we got there in the way we did. He seemed to believe the “New Age” trends he saw in the 1980s and 90s might grow, and that the much-publicized decrease in our ability to educate our students¬†would result in an overall dumbing down of America. He himself did what he could to keep that from happening. I doubt he thought, though, that only two decades after he wrote those words we would have fallen so far and so willingly.

Hat tip to Scott Lowther and his “Up-Ship” blog for tipping me off to this one.

The SR-72! ?

November 5, 2013

sr-72

According to this information from Lockheed, they have a way to combine a regular jet turbine engine with a ramjet that could power a Mach 6 aircraft. Calling it the SR-72 as a nod to the famed SR-71 reconnaissance plane the Lockheed Skunk Works built in the 1960s, this one is to be unmanned – like pretty much every military plane on the drawing boards.

I just hate it that they announced way before they bent any tin, though. The X-33 disaster of promise-oops- can’t deliver is still too fresh in my mind. (In defense of Lockheed, though, a lot of the problem with getting the X-33 demonstrator flying was political. Interference by Congress has a way of screwing up programs like that. Well, any program, really. ) Saying they may have this operational by 2030 sounds like a long way off, but the F-35 Strike Fighter has been in development really for over 12 years. They are just barely getting production aircraft out to the USAF now, seven years after the first prototype flew.

I really hope this will happen, even if just for the jumpstart hypersonic flight would get. But the generation that built the U-2, the SR-71 and even the stealth fighter are pretty much retired or passed on. (Kelly Johnson, the legendary leader at the Skunk Works, died in 1990.)

If anyone can do it I figure Lockheed will. But why announce it so early?
