Idle Curiosity and Coffee

Click photo for a fun blog post about watching someone leave their coffee on the roof of their car by Paul Duncan.

So you remembered that you put the coffee on the roof of the car as you got in…
because the liquid is running down your back window.

Do you know the answer?

Good Morning!


Sturgeon Full Moon and an Optical Effect

The Full Sturgeon Moon

August’s full Moon will appear this evening of Sunday, August 2, before reaching peak illumination at 11:59 A.M. Eastern Time on Monday, August 3. On either August 2nd or 3rd, look toward the southeast after sunset to catch a glimpse of the Sturgeon Moon rising, weather permitting!

August’s full Moon will hang relatively low in the night sky, which makes it look larger due to perspective (Ebbinghaus Illusion). Why is the Moon hanging lower? A full Moon is opposite the Sun, which as we all know, is higher in the sky during summer. So the full Moon runs lower.


The Ebbinghaus illusion is one optical effect that might help explain the moon illusion. In this illustration, the green circles are exactly the same size, but the ones on the right appear larger than those on the left.green


Coffee – How much is the “right” amount?

Four cups of strong coffee a day might be the recipe for a healthy heart, especially for older adults.

That amount may vary from person to person – but it seems to be a good solid number. Also, note that though caffeine is the first thing that comes to mind when you think about coffee, it also contains antioxidants and other active substances that may reduce internal inflammation and protect against disease.

The following focuses on caffeine intake – about 250 – 350 mg a day.

A team of German researchers, led by the molecular biologists Judith Haendeler and Joachim Altschmied, thinks it has discovered clues about how coffee works its caffeine-fueled magic on our heart health and how much caffeine we should drink each day to see the best benefits.

By studying caffeinated lab mice and dosing human tissues with caffeine, the researchers discovered how a jolt of the stimulant could improve the way cells inside our blood vessels work — essentially, by making certain proteins inside older adult cells perform more like young and nimble ones. The study was published Thursday in the journal PLOS Biology.

“When you drink four to five cups of espresso,” Altschmied told Business Insider, “that seems to improve the function of the powerhouses of our cells, and therefore seems to be protective.”

Scientists have for years noticed that people who drink coffee seem to be less likely to die from all sorts of causes, including heart disease, stroke, or diabetes. Perhaps the best evidence yet for this comes from two massive studies: one of more than 400,000 people in the US by the National Institutes of Health, and another of more than 500,000 Europeans. Both studies found that regular coffee drinkers were less likely to die from any cause than people who don’t sip a daily brew.

Coffee is also associated with a whole host of other health benefits, including a lower risk of liver disease (cirrhosis), a lower risk of developing certain kinds of cancer, lower rates of dementia and Alzheimer’s, and a reduced risk of depression. It’s also great for your heart — people who drink three or four cups a day may be 19% less likely to die from cardiovascular disease.

Altschmied said he hoped his new study would debunk the old advice that people with heart problems shouldn’t drink coffee, and he argues that drinking the equivalent of about four shots of espresso a day could help reduce the risk of heart attacks, especially for people who are obese or prediabetic.

“It will not replace other things,” he said. “Keep on doing your sports, eat healthily, and add coffee to your diet.”

If you don’t like the taste, green tea has similar levels of caffeine and could also be an effective way to boost heart health.

It’s important not to overdo it with the new recommendation, as too much coffee can quicken your heartbeat and cause other health problems. But drinking up to six cups a day should be OK, cardiologists say, and may even reduce arrhythmias in people with irregular heartbeats.

One caveat: The study wasn’t done in humans — only in human tissues and lab mice. What works in a hyper-controlled environment of mice, dosed with very specific amounts of caffeine, may not be the same as what happens when you drink a cup of joe at home.

“If I had four cups of espresso and you had four cups of espresso, we cannot guarantee that we reach the same level in the blood,” Altschmied said.

He also offers a word of caution: Because caffeine can make blood vessels grow, providing more oxygen to fuel tumors, the coffee-drinking advice might not hold for people who have cancer.

“Where people have a diagnosed tumor, we would say better take your hands off the coffee,” Altschmied said. “But if you’re otherwise healthy, it will not harm you, and it might help your heart and circulatory system stay better functional for a longer time.”

Pin-Ups by Bill Randall

“Red sky at night, sailor’s delight. Red sky in morning, sailor’s warning.”

Normally, weather moves from west to east. In the mid-latitudes, the prevailing winds are westerlies. This means storm systems generally move in from the West.

The colors we see in the sky are due to the rays of sunlight being split into colors of the spectrum as they pass through the atmosphere and ricochet off the gases, water vapor and particles. The amounts of water vapor and dust particles in the atmosphere are good indicators of weather conditions. They also determine which colors we will see in the sky.

During sunrise and sunset the sun is low in the sky, and it transmits light through the thickest part of the atmosphere. A red sky suggests an atmosphere loaded with dust and moisture particles. The shorter wavelengths, such as blue, are scattered and broken up. We see the red wavelengths. the longest in the color spectrum, are able to continue through the atmosphere.

Red sky at night, sailor’s delight.

A red sky at night means that the setting sun is sending its light through a high concentration of dust particles. This usually indicates high pressure and stable air coming in from the west and good weather will follow.

Red sky in morning, sailor’s warning.

A red sunrise can mean that a high pressure system (good weather) has already passed, thus indicating that a storm system (low pressure) may be moving to the east. A morning sky that is a deep, fiery red can indicate that there is high water content in the atmosphere. So, rain could be on its way.

A BDSM executive toy: Shibari Newton’s Cradle

Two of dievca’s passions: BDSM and Physics!

In early 1967, an English actor, Simon Prebble, coined the name “Newton’s cradle” (now used generically) for the wooden version manufactured by his company, Scientific Demonstrations Ltd. After some initial resistance from retailers, they were first sold by Harrods of London, thus creating the start of an enduring market for executive toys. Later a very successful chrome design for the Carnaby Street store Gear was created by the sculptor and future film director Richard Loncraine. – wikipedia

Submissive Day Collars: for the Science Geek

submissive Day Collar for the Science Geek Cellular Collar n-e-r-v-o-u-s systemDoes this piece remind you of something you once saw in a science textbook? There is a reason, Nervous System bases designs on forms from nature. The Cellular Collar features a complexly patterned structure created from twisting and subdividing a simple hexagonal mesh. It rests elegantly upon the collar bones and stays in place with no clasp. Inspired by forms of microscopic creatures with mineral exoskeletons, radiolarians. This necklace is both intricate and strong. It has taken shape by using a type of 3D printing.

NERVOUS SYSTEM

Somerville, MA, USA Two tech, design, science, and math-savvy MIT alumni founded Nervous System in 2007. Nervous System is a generative design studio that works at the intersection of science, art, and technology. They make jewelry and housewares in the likeness of nature’s forms, from leaf veins to tiny sea creatures. The team turns digital designs mimicking nature’s organic patterns into intricate works in materials like nylon and stainless steel. Drawing inspiration from natural phenomena, they write computer programs that can generate an infinite range of designs.
