Wanda Diaz Merced is a blind astronomer who hears the science of the stars

Wanda Diaz Merced is an astronomer at the International Astronomical Union (IAU) Office for Astronomy Outreach in Mitaka, Japan. Diaz Merced is blind and uses a technique to transform data from astronomical surveys into sounds for analysis. Over at Nature, Elizabeth Gibney interviewed Merced about how “converting astronomical data into sound could bring discoveries that conventional techniques miss.” From Nature:

How did you begin your work with sonification?

Sonification has been around for a long time. In 1933, for example, US physicist Karl Jansky reported detecting the first radio waves from space, as an audible hiss in his antenna. But at some point, visualization came to dominate the way we interpret astrophysical data. When I was an intern at NASA in 2005, my mentor, Robert Candey, wanted me to create a prototype data analysis tool that would familiarize blind people with space-physics data. So we developed software that could map astronomical data into sound — its pitch, rhythm and volume. Then, in my 2013 PhD dissertation at the University of Glasgow, UK, I proved that it is useful….

Can you describe a real-world example?

There are many. Sonification can help us to study the habitability of an exoplanet, by understanding how much high-energy cosmic and solar rays interact with its magnetic field or atmosphere. Such interactions cause fluctuations of electromagnetic emission from that star system that vary in a way that relates to frequency . BBut because astronomers usually separate out different frequency components into many graphs, this is easy to miss. With sonification, we can listen to all the different frequencies together and pick out the signal from the noise.

Why you should almost always order one large pizza instead of two mediums

screenshot-118.jpg?fit=802%2C538&ssl=1

Many pizza places offer special “deals” if you order two medium pies. You might think that two mediums deliver more cheesy goodness than one large pie, but usually you’d be mistaken. From Primer, a mathematical comparison of two 12″ pizzas and one 18″ pizza:

Area of two 12” pizzas:

12/2 = 6 6×6=36 36xπ = 113.1 in² x 2 = 226.2 in²

Area of one 18” pizza:

18/2=9 9×9=81 81xπ = 254.5 in²

And as we know, more pizza is always better.

Getting rid of silverfish with lavender oil

1280px-LepismaSaccharina-removebg-previe

For years we’ve had silverfish darting around our guest bathroom floor. I bought some silverfish traps (little cardboard boxes with sticky goo to ensnare them) and they helped, but didn’t stop them. In 2017 I read that lavender oil is a good silverfish repellent. It’s only $7.99 for a small bottle on Amazon, so I decided to give it a try. I wetted the end of a Q-Tip with the oil and ran it around the perimeter of the bathroom floor, adding a little extra to a seam between the floor and the wall. It smelled nice and did not see a single silverfish for two weeks. I finally saw one, reapplied lavender oil on the perimeter of the floor, and it keep the little bastards aways for an even longer time. Now I hardly ever see them, and treat the floor every few months.

Highlights from the Red Bull Rubik’s Cube World Cup

The Red Bull Rubik’s Cube World Cup was held November 17 in Moscow. Competitors squared off in four events:

3×3 Speed Cubing

– solving the Rubik’s Cube as fast as possible;

Fastest Hand

– a challenge that solves the Rubik’s Cube with only one hand;

Re-Scramble

– pits competitors trying to replicate a computer generated pattern from another cube as fast as possible and;

3×3 Female

– a track exclusively for female competitors.

What an action-packed evening at the Red Bull Rubik’s Cube World Cup Finals from the Yota Arena in Moscow 🏆

25 Fun Facts About Food from Gastropod

The Gastropod podcast turns five years old this month and to celebrate they’ve compiled a list of 25 of their favorite fun food facts from the show’s archives. Here’s the entire list with links to each of the shows (shared with permission):

1. The Mafia got its start in the 1860s, in the lemon groves of Sicily. At the time, growing lemons was the most lucrative form of agriculture in Europe, thanks to scurvy and the British Navy. (Museums and the Mafia: The Secret History of Citrus)

2. Using gold (or gold-plated) cutlery makes food taste sweeter. (Episode 1: The Golden Spoon)

3. Olive oil is fruit juice. (Green Gold: Our Love Affair with Olive Oil)

4. Saliva is filtered blood. (Guts and Glory)

5. The enamel on our teeth is the hardest tissue in our entire bodies — at 95 percent mineral, it’s basically a rock. (The Truth is in the Tooth: Braces, Cavities, and the Paleo Diet)

6. The invention of forks changed the shape of our jaws. (Episode 1: The Golden Spoon)

7. Medieval nuns used to get high on saffron, to help them get through their prayer marathons. (Meet Saffron: The World’s Most Expensive Spice)

8. In the absence of kitchen timers or affordable clocks, recipes in the earliest cookbooks gave timings in the form of prayers, like two Lord’s Prayers or four Hail Marys. (Cooking the Books with Yotam and Nigella)

9. True wasabi (most wasabi in the U.S. is just colored horseradish) has a flavor “window”: it has no taste for the first five minutes after being grated, then the flavor explodes — but it fades after another ten to fifteen minutes. You have only a few minutes to enjoy wasabi at its peak! (Espresso and Whisky: The Place of Time in Food)

10. The word “avocado” comes from the Nahuatl word for testicle. (Ripe for Global Domination: The Story of the Avocado)

11. The word “cocktail” comes from the practice of putting a piece of ginger up a horse’s butt to make it cock its tail up, and seem younger and friskier. (The Cocktail Hour)

12. Jell-O was originally sold as a patent medicine that was good for hair and nails. (Watch it Wiggle: The Jell-O Story)

13. The earliest recorded recipe for ice-cream was flavored with ambergris, which is a salt- and air-cured whale excretion (no one is quite sure whether it’s vomit or poo). (The Scoop on Ice Cream)

14. New York City’s first soda fountains used marble scraps left over from building St. Patrick’s cathedral to produce their carbonation. (Gettin’ Fizzy With It)

15. The superiority of New York City’s bagels has nothing to do with the city’s water. (The Bagelization of America)

16. Donald Rumsfeld was the man behind the launch of Nutrasweet. (Sweet and Low (Calorie): The Story of Artificial Sweeteners)

17. George W. Bush and a trade deal involving Harley Davidsons were the reason that the Indian Alphonso, the so-called “king of mangoes,” can now finally be imported to the U.S. (Mango Mania: How the American Mango Lost its Flavor — and How it Might Just Get it Back)

18. Jack Daniel learned how to make whiskey from an enslaved African, Nearest Green, who went on to become the company’s first master distiller. (The Secret History of the Slave Behind Jack Daniel’s Whiskey)

19. The first pasta machine was designed by Leonardo da Vinci. (Remembrance of Things Pasta: A Saucy Tale)

20. In England in the 1600s, a special breed of dogs were used to turn spits of roasted meat in front of the open fire. These turnspit dogs are now extinct; their closest relation is thought to be a corgi. (Hotbox: The Oven from Turnspit Dog to Microwave)

21. In America in the early 1900s, the pawpaw was voted the native fruit most likely to succeed, ahead of the blueberry. (Pick a Pawpaw: America’s Forgotten Fruit)

22. The story that carrots are good for eyesight was World War II military disinformation, spread by the British to prevent the Germans from realizing that the Royal Air Force were shooting down so many enemy planes because their cockpits were now equipped with radar and red lighting. (How the Carrot Became Orange, and Other Stories)

23. Mustard became spicy over the course of a 90-million-year evolutionary arms race against caterpillars. (Cutting the Mustard)

24. Plants can hear themselves being eaten. (Field Recordings)

25. A raw human male contains, on average, 143,770 calories. (Cannibalism: From Calories to Kuru)
