Einstein's Design for a Fridge to Last 100 Years

After establishing the theory of relativity as a founding principle of modern physics, Albert Einstein turned his thoughts to higher matters: home appliances. In 1926, the Nobel Prize-winning scientist put his considerable mental energies towards developing the refrigerator to end all refrigerators—energy-efficient, environmentally friendly, and durable enough to last a century.

Einstein’s interest in consumer goods was initially piqued by a news story recounting the death of a family in Berlin from the poisonous fumes of their poorly sealed refrigerator—a danger which was growing increasingly prevalent as households exchanged their ice boxes for modern refrigerators containing volatile chemical coolants. He proposed a solution that avoided the use of deadly methyl chloride, ammonia, or sulfur dioxide, enlisting the aid and expertise of young Hungarian physicist, friend, and thermodynamics specialist Léo Szilàrd to draft a prototype of a safer, better “absorption refrigerator” instead.

In the traditional style of refrigerator, a mechanical compressor pressurizes potentially toxic gases to initiate the cooling process. So long as the fridge remains safely sealed, the risks to users are minimal, but a refrigerator’s moving parts often wear out its seal and expose its fatal contents to the air. Einstein and Szilàrd’s design would require no moving parts, instead using a heat source to naturally pressurize the gas contained within the series of circuits. With no immediate source of wear and tear, the Einstein-Szilàrd refrigerator would last as long as its external casing did—up to 100 years, experts estimate.

Over the course of their partnership, the two scientists took out 45 patents for refrigeration technology in six countries, eventually selling their key patents to appliance manufacturer AB Electro Lux. However, their design remained less efficient than compressor-type models, and the combined advent of the Great Depression’s effect on industrial budgets and the introduction of chlorofluorocarbons as less toxic chemical alternatives put an end to Einstein and Szilàrd’s domestic technology dreams—until a recent resurgence of interest by researchers at Oxford University, who have picked up on the idea of a fridge that can function without electricity or greenhouse gases as a green solution to our increased global dependence on cooling technologies. Though the remake of the original Einstein fridge has yet to make it to market, every kitchen might soon be keeping their drinks cold and their pie crusts chilled in Einstein’s new and improved brainchild.

10 Questions About Columbus Day

Every American student learns that Christopher Columbus sailed the ocean blue and landed in the New World in 1492. Winifred Sackville Stoner, Jr.'s poem "History of the U.S." has made it impossible to forget the date (although the couplet actually predates her birth), and many federal workers get a day off every October to recognize the explorer's arrival in the New World. You know the who and where, but here are 10 more answers to pressing questions about Columbus Day.

1. When did Christopher Columbus become a cultural icon?

By the early 1500s, other navigators like Amerigo Vespucci and Francisco Pizarro had become more popular and successful than Columbus had been with his off-course voyages. According to The New York Times, historians and writers in the latter part of the 16th century restored some of Columbus’s reputation with great words of praise for the explorer and his discoveries, with his fellow Italians proving particularly eager to celebrate his life in plays and poetry.

2. How did Christopher Columbus's popularity reach the United States?

Blame the British. As the American colonies formed an identity separate from their mainly English roots, colonists looked to figures like the "appointed of God" Columbus to symbolize their ideals. "By the time of the Revolution," writes John Noble Wilford, "Columbus had been transmuted into a national icon, a hero second only to Washington." Columbus's American legacy got another shot in the arm in 1828 when a biography (peppered with historical fiction) by Washington Irving transformed Columbus into an even more idealized figure who sought to "colonize and cultivate," not to strip the New World of its resources.

3. When was the first Columbus Day?

The first recorded celebration took place in 1792 in New York City, but the first holiday held in commemoration of the 1492 voyage coincided with its 400th anniversary in 1892. President Benjamin Harrison issued a proclamation in which he called Columbus a "pioneer of progress and enlightenment" and suggested that Americans "cease from toil and devote themselves to such exercises as may best express honor to the discoverer and their appreciation of the great achievements of the four completed centuries of American life."

If Harrison had had his way, though, the holiday would have been celebrated on October 21. He knew that Columbus landed under the Julian calendar, not the Gregorian calendar we use today—making October 21 the correct date for anniversary celebrations.

4. Did anyone actually celebrate Columbus Day in the 19th century?

Italian Americans embraced Columbus as an important figure in their history and saw celebrating him as a way to "be accepted by the mainstream," the Chicago Tribune notes. The Knights of Columbus, an organization formed by Irish Catholic immigrants in 1882, chose the Catholic explorer as their patron "as a symbol that allegiance to their country did not conflict with allegiance to their faith," according to the group's website. Following President Harrison’s 1892 proclamation, they lobbied for Columbus Day to become an official holiday.

5. When did Columbus Day become an official holiday?

The holiday first found traction at the state level. Colorado began celebrating Columbus Day, by governor's proclamation, in 1905. Angelo Noce, founder of the first Italian newspaper in the state, spearheaded the movement to honor Columbus and Italian American history. In 1907, the Colorado General Assembly finally gave in to him and made it an official state holiday.

6. When did Columbus Day become a federal holiday?

With Franklin D. Roosevelt as president, lobbying from the Knights of Columbus paid off, and the United States as a whole observed Columbus Day in 1934. Thirty-four years later, Lyndon B. Johnson signed the Uniform Holiday Bill, which designated Columbus Day as a federal holiday.

7. Why does the date of Columbus Day change every year?

Columbus Day was originally celebrated on October 12, the day Columbus landed in the New World, but the Uniform Holiday Bill took effect in 1971 and changed it to the second Monday in October, as well as moved the dates of Washington’s Birthday, Memorial Day, and Veterans Day to Mondays (Veterans Day would be moved back to November 11 in 1980 after criticism from veterans’ groups). The act of Congress was enacted to "provide for uniform annual observances of certain legal public holidays on Monday, and for other purposes."

8. Does every state observe the Columbus Day holiday on the same weekend?

In Tennessee, Columbus Day comes with an asterisk. The state’s official holiday observance calendar reads that Columbus Day is the second Monday of October, or "at the governor's discretion, Columbus Day may be observed the Friday after Thanksgiving."

9. Which states don't celebrate Columbus Day?

In Hawaii, the second Monday of October is known as Discoverer’s Day, "in recognition of the Polynesian discoverers of the Hawaiian Islands, provided that this day is not and shall not be construed to be a state holiday," KHON2 writes. According to the Pew Research Center, only 21 states treated Columbus Day as a paid state holiday in 2013. South Dakota, New Mexico, Maine, and the District of Columbia celebrate Native Americans Day or Indigenous People's Day as a paid holiday. Several cities, like San Francisco and Cincinnati, celebrate Indigenous People's Day.

10. How do other places around the world celebrate Columbus Day?

In Italy, Columbus Day (or Giornata nazionale di Cristoforo Colombo) is listed as one of the national or international days of celebration and is still on October 12, but it's not a public holiday. Some countries have chosen to observe anti-Columbus holidays like the Day of the Indigenous Resistance in Venezuela and Nicaragua, Pan American Day in Belize, and the Day of Respect for Cultural Diversity in Argentina.

Quid Pro Quo Has a Nefarious Etymology

While some altruists will happily lend a hand without expecting anything in return, most of the world runs on the idea that you should be compensated in some way for your goods and services.

That’s quid pro quo, a Latin phrase which literally means “something for something.” In many cases, one of those “somethings” refers to money—you pay for concert tickets, your company pays you to teach your boss how to open a PDF, etc. However, quid pro quo also applies to plenty of situations in which no money is involved. Maybe your roommate agreed to lend you her favorite sweater if you promised to wash her dishes for a month. Or perhaps, in return for walking your neighbor’s dog while he was on vacation, he gave you his HBO login credentials.

No matter the circumstances, any deal in which you give something and you get something falls under the category of quid pro quo. According to The Law Dictionary, “it is nothing more than the mutual consideration which passes between the parties to a contract, and which renders it valid and binding.” In other words, if everyone on both sides understands the expectation that something will be given in return for a good or service, your contract is valid.

Based on that definition, quid pro quo hinges on transparency; all parties must understand that there’s an exchange being made. However, this wasn’t always the case. As the Columbia Journalism Review reports, Merriam-Webster’s dictionary entry states that quid pro quo was used in 16th-century apothecaries to denote when one medicine had been substituted for another, “whether intentionally (and sometimes fraudulently) or accidentally.”

So, if you were an unlucky peasant with a sore throat, it’s possible your herbal remedy could’ve been swapped out with something less effective—or even dangerous. Though Merriam-Webster doesn’t offer any specific examples of how or why this happened, it definitely seems like it would have been all too easy to “accidentally” poison your enemies during that time.

Just a few decades later, the term had gained enough popularity that people were using it for less injurious instances, much like we do today.
