Buster Keaton (October 4, 1895 – February 1, 1966), “The Great Stone Face”
A man famous for directing and acting in silent films, his deadpan expression, physical comedy, and, featured above, his stunt performance. This man did all his own stunts, and they are amazing.

Computer memory and information storage
Today, we are comfortable about expressing memory and disk space in terms of “bytes”, where each byte is made up of 8 bits. In contrast the unit of memory in the AGC was the “word” (byte was never used), which was made up of 15 bits for memory storage and one extra bit for an error detection code called “parity”. When MIT began the work on the computer, it was thought that 4 kilobytes of read only memory (ROM) and 512 bytes (or 0.5 kilobytes) of erasable random access memory (RAM) would be adequate. But as the software grew the need for more ROM to store it doubled three times to 8, 16 and then 32KB. The final memory specifications of the AGC were 36,864 Bytes (36KB) of ROM and 2,048 Bytes (2KB) of erasable memory.
