While some physicists may be working on string theory or quantum mechanics, Manuel Linares has decided to turn his attention to something else entirely – ice cream.
The Spanish physicist and now professional cook has announced that he has invented a ‘magical’ ice cream that changes color as you lick it. Before it’s served, the treat is a light blue color, but this quickly changes when the server adds a spray of ‘love elixir, as Mr Linares calls it. The spray transforms the ice cream into a dark pink shade in around 10 to 15 seconds.
When the customer licks the ice cream, it again changes into other pink shades as it melts The formula, which remains a secret, is made entirely from natural ingredients, according to Mr Linares. The Spaniard said he gained his inspiration from the British ice cream genius Charlie Francis, the creator of a fluorescent ice.
The chef is currently offering his ice cream at his shop in in the town of Calella de Mar, in the east Spanish province of Barcelona. He is also working on another two ice creams. One will react to ultraviolet lights in clubs, while another will turn from white to pink as it’s eaten.

Analyses of the National Child Development Study show that more intelligent men and women express preference to remain childless early in their reproductive careers, but only more intelligent women (not more intelligent men) are more likely to remain childless by the end of their reproductive careers. (…)
Because women have a greater impact on the average intelligence of future generations, the dysgenic fertility among women is predicted to lead to a decline in the average intelligence of the population in advanced industrial nations.

When swiped, a terminal uses the magnetic stripe of the card to first route the transaction through the proper card network, and then to the financial institution that is listed on the card so that the transaction can be authorized.
Every card, no matter the network or bank, must be in agreement with the “ Luhn System, ” which determines the validity of a credit card. It’s a mathematical algorithm where various combinations of numbers must add up to a number ending in 0. If the total of the combinations adds up to anything other than a multiple of 10, the card is invalid.
Generally, the first number or two of a credit or debit signifies the card provider, followed by digits that determine everything from the currency being used, to the bank processing the transaction, to the individual’s account number.
- American Express: American Express uses the first two numbers of the card to identify itself. That two-digit number will be either 34 or 37. The third and fourth digit signify the type of card and the currency being used, according to Clearpoint Credit Counseling. The next six digits, five through 11, are the number of the account, while the 12th through 14th digits represent the card number within said account.
- Visa: Visa cards use a very similar formula. The first digit assigned to all Visa cards is four, and the second through sixth numbers are connected to the financial institution. Then, either the seventh through 12th numbers, or the seventh through 15th, are the account number.
- MasterCard: MasterCards use the number five as the first in their 16-digit sequence. The second and third, second and fourth, or second and fifth then represent the bank number. Following the third, fourth, or fifth digit, every number up through 15 is the account number.
- Other Cards: All Discover cards start with the number six and are 16 digits in length, while petroleum cards start with the number seven and airline cards start with the number one.
Network and financial institution numbers are assigned by the American National Standards Institute, a nonprofit based in Washington, D.C. The rest of the numbers, up through the last digit, make up the account number specific to the customer holding that card.
Generally, the final digit is a randomly selected number known as a “check digit,”. It helps validate the account to ensure against errors in entering the account number. It also helps to limit fraud.
Debit cards are coded the same way as credit cards. Although newer than credit cards, debit cards have steadily increased in popularity. The volume of debit and credit transactions is now about even. U.S. consumers carry some 1 billion credit and debit cards in their wallets.
