...talk turned to molybdenum, which is not the hardest metal known to man but has the advantage of not even beginning to melt at temperatures up to 4,700°F. Eventually the atom experts decided to put their drilling theories to a test; they constructed a 2-in. cylindrical drill bit of molybdenum, and to their surprise their very first demonstration was a success. With a 5-kw. generator, they heated the face of the bit to 2,190°F, then forced it down against a specimen of hard basalt rock. Like a hot pick thrusting through...
...problems for a while, five nuclear scientists at the Atomic Energy Commission's Los Alamos Scientific Laboratory were discussing the difficulties of Project Mohole, the National Science Foundation's plan to bore through six miles of the earth's crust northeast of Hawaii. What kind of drill would stand...
...Alamos men are already speculating beyond Mohole. They feel that their drill can be put to work some day to tap the geothermal energy that abounds deep in the earth, causing hot springs and geysers. As for immediate uses, the inventors are uncertain, but they answer at least one request a day for information about their molybdenum bit from miners and wildcatters...
Beberman says: "The old system was deadly-drill, drill, drill. What I'd like to do is take all these people who say, 'Let's have new math, let's get it into the schools,' and shake them up and say, 'First let's make sure the teachers who are going to teach it know what's going on.'" Badly taught, new math plants confused concepts and creates individuals who cannot even keep their check stubs figured, and Beberman never intended that. "The key thing is computation," he says...
However, activities such as the drill team and millitary balls are expected to remain available on an option basis...
