Why Asparagus Makes Your Urine Smell Funny

Why Asparagus Makes Your Urine Smell Funny When you eat asparagus, your urine will smell funny. However, not everyones noses can detect the odor of asparagus pee. The chemical that produces the effect is called asparagusic acid. Asparagusic acid is not volatile, so if you sniff a spear of aparagus, you wont smell anything noteworthy. However, when your body digests asparagus, aspargusic acid is broken down into simpler compounds, which are volatile, so they transfer from urine into the air, where they make their way to your nose so  you can smell them. These compounds  include dimethyl sulfide, dimethyl disulfide, dimethyl sulfone, and  dimethyl sulfoxide. The sulfurous compounds or mercaptans are related to the chemicals that make  skunk spray and rotten eggs  so odious. Asparagus Doesnt Make Everyones Pee Stink While it is believed everyone excretes these compounds in their urine after eating asparagus, somewhere between 22% and 50% of the population lack  the chemoreceptors to detect the funky smell. Also, some people may metabolize asparagusic acid in a way that produces lower quantities of the distinctive-smelling molecules. Whether or not you can smell the distinctive funky odor of asparagus pee depends on your genetics. Inability to smell the chemical results from a single base pair genetic mutation, which is passed on in families.  While you might not consider yourself fortunate if you can smell it, the upside is youre more likely able to smell other sulfurous molecules, which might protect you from toxic chemicals.

Writing Greek Letters on the Computer

Writing Greek Letters on the Computer If you write anything scientific or mathematical on the internet, you will quickly find the need for several special characters that are not readily available on your keyboard. ASCII characters for  HTML  allow you to include many characters that dont appear on an English keyboard, including the  Greek alphabet. To make the correct character appear on the page, start with an ampersand () and a pound sign (#), followed by a three-digit number, and ending with a semicolon (;). Creating Greek Letters This table contains  many Greek letters  but not all of them. It only contains uppercase and lowercase letters that are not available on a keyboard. For  example, you can type the capital alpha (A) in Greek  with a regular capital  Ã¢â‚¬â€¹A  because these letters look the same in Greek and English. You can also use the code #913 or Alpha. The results are the same. Not all symbols are supported by all browsers. Check before you publish. You may need to add the following bit of code in the head part of your HTML document: meta http-equivcontent-type contenttext/html; charsetutf-8 HTML Codes for Greek Letters Character Displayed HTML Code capital gamma Γ #915; or Gamma; capital delta Δ #916; or Delta; capital theta ÃŽËœ #920; or Theta; capital lambda Λ #923; or Lamda; capital xi Ξ #926; or Xi; capital pi ÃŽ   #928; or Pi; capital sigma ÃŽ £ #931; or Sigma; capital phi ÃŽ ¦ #934; or Phi; capital psi ÃŽ ¨ #936; or Psi; capital omega ÃŽ © #937; or Omega; small alpha ÃŽ ± #945; or alpha; small beta ÃŽ ² #946; or beta; small gamma ÃŽ ³ #947; or gamma; small delta ÃŽ ´ #948; or delta; small epsilon ÃŽ µ #949; or epsilon; small zeta ÃŽ ¶ #950; or zeta; small eta ÃŽ · #951; or zeta; small theta ÃŽ ¸ #952; or theta; small iota ÃŽ ¹ #953; or iota; small kappa ÃŽ º #954; or kappa; small lamda ÃŽ » #955; or lambda; small mu ÃŽ ¼ #956; or mu; small nu ÃŽ ½ #957; or nu; small xi ÃŽ ¾ #958; or xi; small pi Ï€ #960; or pi; small rho Ï  #961; or rho; small sigma ÏÆ' #963; or sigma; small tau Ï„ #964; or tau; small upsilon Ï… #965; or upsilon; small phi φ #966; or phi; small chi χ #967; or chi; small psi ψ #968; or psi; small omega ω #969; or omega; Alt Codes for Greek Letters You can also use Alt codes- also called quick codes,  quick keys, or keyboard shortcuts- to create Greek letters, as displayed in the  table below, which was adapted from the website  Useful Shortcuts. To create any of these Greek letters using the Alt codes, simply press the Alt key while simultaneously typing the listed number. For example, to create the Greek letter Alpha (ÃŽ ±), press the Alt key and type 224 using the keypad at the right side of your keyboard. (Do not use the numbers at the top of the keyboard located above the letter keys, as they will not work for creating Greek letters.)

Before the fifth century B.C., there were two similar Greek alphabets, the Ionic and Chalcidian. The Chalcidian alphabet may have been the forerunner of the Etruscan alphabet and, later, the Latin alphabet. It is the Latin alphabet that forms the basis of most European alphabets. Meanwhile, Athens adopted the Ionic alphabet; as a result, it is still used in modern Greece. While the original Greek alphabet was written in all capitals, three different scripts were created to make it easier to write quickly. These include uncial, a system for connecting capital letters, as well as the more familiar cursive and minuscule. Minuscule is the basis for modern Greek handwriting. Why You Should Know the Greek Alphabet Even if you never plan to learn Greek, there are good reasons to familiarize yourself with the alphabet. Mathematics and science use Greek letters like pi (Ï€) to complement the numeric symbols. Sigma in its capital form (ÃŽ £) can stand for sum, while the uppercase letter delta (Δ) can mean  change. The Greek alphabet is also central to the study of theology. For example, the Greek used in the Bible- called  Koine (or common) Greek- is different than  modern Greek. Koine Greek was the language used by writers of the Old Testament Greek Septuagint  (the earliest existing Greek translation of the Old Testament) and the Greek New Testament, according to an article titled The Greek Alphabet published on the website  BibleScripture.net. So, many theologians need to study ancient Greek to get closer to the original biblical text. Having ways to quickly produce Greek letters using HTML or keyboard shortcuts makes this process much easier. Additionally, Greek letters are used to designate fraternities, sororities, and philanthropic organizations. Some books in English are also numbered using the letters of the Greek alphabet. Sometimes, both lowercase and capitals are employed for simplification. Thus, you may find that the books of the Iliad are written Α to ÃŽ © and those of the Odyssey, ÃŽ ± to ω.
