So, there you have it, my first (and probably last, since I'm apparently shitlisted) foray into psychic-busting. I'm not going to tell people to stop seeing psychics - if it makes you happy and you have the cash, go wild. Whether you go in as a believer or as a shithead like me, the psychics are the ones making bank, so either way, in the end, they win. And who knows, maybe I have a sister I don't know about whose birth and death dates I guessed right, in which case, I should set up my own psychic shop. I'm sure Emily would approve.
Magnetic stripe technology, usually called mag-stripe, is so named because of the stripe of magnetic oxide tape that is laminated on a card. There are three tracks of data on the magnetic stripe. Typically the data on each of the tracks follows a specific encoding standard, but it is possible to encode any format on any track. A mag-stripe card is cheap compared to other card technologies and is easy to program. The magnetic stripe holds more data than a barcode can in the same space. While a mag-stripe is more difficult to generate than a bar code, the technology for reading and encoding data on a mag-stripe is widespread and easy to acquire. Magnetic stripe technology is also susceptible to misreads, card wear, and data corruption. These cards are also susceptible to some forms of skimming where external devices are placed over the reader to intercept the data read.
When searching for a memory card, it's important to consider more than just capacity. It's nice to have a big warehouse to store data, but speed, data protection, and durability are just as important for high performance in demanding conditions. Speed refers to the rate at which data can be stored. The faster your card, the more images you'll be able to shoot in a single burst, and the less lag and fewer interruptions you will experience.
Some scientists of the period who investigated spiritualism also became converts. They included chemist Robert Hare, physicist William Crookes (1832–1919) and evolutionary biologist Alfred Russel Wallace (1823–1913). Nobel laureate Pierre Curie took a very serious scientific interest in the work of medium Eusapia Palladino. Other prominent adherents included journalist and pacifist William T. Stead (1849–1912) and physician and author Arthur Conan Doyle (1859–1930).
