Imagine you are an alien with a modest grasp of the English language. You have never been to Earth nor met any humans. You learned English from a straight translation of a dictionary. You enjoy reading human books even if you don’t fully understand some elements. One day you find a cookbook. The idea of eating real Earth food is enchanting. After much deliberation, you choose one of the simpler recipes; an omelette.
So, do you, an alien with a modest grasp of the English language, think you could cook an omelette? Let me answer for you: probably not but with a little help maybe.
We will ignore the difficulty in obtaining all the ingredients and the ambiguity of a recipe that calls for eggs. What kind of eggs? Fish eggs? Snake eggs? Dinosaur eggs? No, you won’t have to deal with that conundrum. Fresh chicken eggs will be provided along with the proper spices and fillings.
So, where does the difficulty in preparing an omelette come from? For starters is there air in your alien kitchen? If there is air, what is the air pressure? What is the temperature in your kitchen? Air pressure, temperature, and humidity can affect cooking times and ingredient stability. Even the small variations on Earth are enough to require conversion charts.
Air pressure is measured in pounds per square inch which means nothing to you. A pound is 0.4536 kilograms and a kilogram is … you don’t happen to have a Kibble balance do you and do you have an understanding of Plancks Constant? Can you measure the precise number of atoms in an object? You know what, forget about that nonsense. Here’s a barometer/thermometer combo. Pressure should be between 29.2 and 30.2; temperature between 70 and 90 degrees Fahrenheit.
Not that the environment is close enough to Earth’s you can begin. Your omelette recipe says to heat a tablespoon of oil over medium-high heat. How hot is “medium-high heat”? Some recipes, mostly baked dishes, will specify a temperature in Fahrenheit. Do you know how to calibrate a temperature measurement device in Fahrenheit? Don’t worry most humans don’t know how Fahrenheit is calibrated, let alone the temperature of medium-high heat, so we’ll allow you a human stove/oven powered by the latest in fusion batteries. I’ll even throw in a frying pan.
Now you’re ready to heat two tablespoons of oil over medium-high heat. Wait, you do have measuring spoons right? No, well look at the inside front cover of the cookbook and you’ll see that one tablespoon is one-sixteenth of a cup or fifteen milliliters or half a fluid ounce. No measuring cups either huh?
Well, one fluid ounce is 29.5735 cubic centimeters. There are one hundred centimeters in a meter and one thousand meters in a kilometer. Light travels at 299792 kilometers per second. A second is … okay, I’m just going to give you a clock but you have to do the rest of the work.
At this point, you have a properly pressurized and heated kitchen with a working stove, frying pan, measuring utensils, and clock. I have one more gift for you; a set of cooking utensils(spatula, spoon, knife) and a plate.
Now you have everything you need to cook an omelette.
