Interesting Fact - The Human Brain
According to neuroscientists from the Salk institute, the human brain has 10 x more memory capacity than previously thought.
(They measured the storage capacity of each synapse - the connections within the brain that are responsible for storing memories - and discovered that, on average, one synapse can hold about 4.7 bits of information. This means that the human brain has a capacity of one petabyte, or 1,000,000,000,000,000 bytes.
One petabyte is about the same as about 20 million four-drawer filing cabinets filled with text or about the same as 13.3 years of HD-TV recordings, or 4.7 billion books. One big problem here: I can barely remember what I had for lunch yesterday.
It all sounds very exciting, until you realise that Google handles 20 petabytes of data every day. And a mere 50 petabytes can hold the entire written works of humankind, from the beginning of recorded history, in all languages.
I think we need to be able to upgrade our brains, or add bits, like plugging in a new drive, or an SD card.)
