What are those two shining lights on world Ceres?

—Mark Wesolowski ’91, Chicago

Astronomers, favor all researchers, are explorers. Visiting new people promises unintended mysteries, through each brand-new exploration initially difficult to explain. The 2 bideal spots, in a crater on the dwarf planet Ceres, are the latest instance. Finding and also solving such mysteries is just one of the factors we check out the far reaches of our solar mechanism.

The bideal spots on Ceres are sunlight reflected from the edge of an influence crater. Yet what shows this light? Is it piled ice or salt, freshly churned up from beneath the surface of Ceres by a meteor impact? Or is the ice reflected by somepoint else? Only better expedition of Ceres will tell.

We view a comparable phenomenon on Umbriel. This is among the heavily cratered moons of Uranus. There, ircontinual patches of sunlight shine from the Wunda Crater. Perhaps the bright spots on Ceres will aid us much better understand what is also happening on Umbriel.

I hope that the Dawn space probe reveals the resource of these lights as the probe gets a closer look at Ceres. We can find that water, in the create of buried ice, is prevalent throughout our Solar System. Then again … maybe not. Solving mysteries like this is why we check out the many and differed people that orbit our sunlight.

Why can’t I tickle myself? I’m among the most ticklish people I know! My friends (and also wife) can’t tickle themselves either. How come?

—J Thomas (Tom) Stoltz ’90, Bangkok, Thailand

What you think you are seeing or feeling is not the real human being. It is being preprocessed by your nervous system.

Your nervous system does not work-related choose a storage device. It is not a electronic camera, soaking up every little thing about you. Your brain just pays attention to important things—as soon as somepoint is novel or brand-new. Anything that is acquainted, your brain sees as usemuch less or unvital information.

When you are perdeveloping an action, your brain sends out signals to your muscles, and the muscles move. But that is not all—a copy of that signal, dubbed an “efference copy,” is maintained and also subtracted from signals of your sensory system. If your actions take place as expected, the efference copy matches the sensory information and no sensory indevelopment reaches the brain.

I touch the computer system computer mouse, and it is only the computer system computer mouse. But say you reach down for your computer system mouse, and there is a spider on it. That is incredibly different than what you suppose. You feel that spider. Your “efference copy” does not match; your brain realizes the distinction and also pulls your hand back.

When we attempt to tickle ourselves, we have actually an expectation of what will take place. The expectation is met. That implies the efference copy matches, so the tickling sensation does not reach the brain. No reactivity.

On the flip side, the expectation hregarding come from our own nervous system for the brain to have actually a possibility to disregard it. If we watch someone coming to tickle us, we will still laugh because it was not our brain that sent out the signal, so tbelow is no efference copy, and also the message reaches the brain. You laugh.

This woodblock print, titled “A Plum,” is by the 20th-century Japanese printmaker Junichiro Skein (1914–1988).


My fiance (Dan Jones ’07) and also I were recently doing a spring cleaning of our basement and also discovered a item of art that belonged to his grandfather. I’ve tried to execute some study on the artist however don’t really understand where to start. Any information on the background of this piece would certainly be much appreciated!

This woodblock print is by the 20th-century Japanese printmaker Junichiro Skein (1914–1988). It is titled A Plum. I discovered it on artnet.com under auctions. You might uncover the exact price this print offered for if you pay for a (one-day pass) to the auction database. His auction prices for woodblocks array from a few hundred dollars to a couple of thousand also.

All I did was guess the lettering of the signature until I uncovered a likely complement. I kbrand-new it was Japanese because of the insignia.

Who created soft soap and also why?

—John Klein (father of Alec Klein ’15), Vernon Hills

(Editorial note: Ah John, we love the John Cusack movie The Sure Thing also, and that is arguably one of the ideal quotes in the movie. Perhaps we’ll never before really understand why liquid soap was designed, yet we deserve to talk around why liquid soap looks the means it does.)

The beginnings of soap as a cleaning agent can be traced ago to the ancient world (~600 B.C., Greek city states). However before, liquid soaps were not commercially accessible until the late 19th century. The most renowned liquid soap at this time was Palmolive soap (from palm and olive oils) occurred by a researcher called B.J. Johnboy.

As the chemistry of soaps has actually come to be more developed, liquid soaps might contain chemical compounds known as saponified vegetable oils. It is likewise possible that they might contain chemical agents like sodium laury sulfate as an emulsifying detergent to dissolve oil and also dirt for cleaning. There are countless other ingredients, such as oils, anti-bacterial agents prefer triclosan, fragrances, and colors—both natural and also synthetic—to suit the interest of the customer.

When all combined these chemical agents create liquid soap, the product has actually an oil consistency, primarily due to the properties of the emulsifying detergent that’s being offered as the crucial ingredient.

What effect perform you think branding had on the last presidential election, and carry out you think it will have actually an affect on the next?

—Tina Krumdick ’85, Lisle

We supplied to understand branding as a one-method task involved in by the communicator in question, whether a perkid or company. The even more conventional methods of responding to political strikes (using push conference, or periodically, defensive advertising) have trouble repairing this damage because of lack of accessibility to their opponent’s finest resource: the social network feed.

Social media has adjusted branding, specifically in disputed projects wright here each party’s objective is to make their enemies seem less preferable. The candidate with the better social media netoccupational and also message designs can define his/her opponent’s public picture in ever more effective ways.

A excellent instance of this is Republihave the right to nominee Mitt Romney’s statement that as governor of Massachusetts he sought and acquired “binders complete of women” in order to improve hiring of women in his management. He sassist this in order to compare his efforts favorably through what President Barack Obama had not completed in regards to sex equity. This tiny expression came to be a widespcheck out social media meme taken to show Romney as viewing woguys as some sort of objective commodity, which was exactly the specific oppowebsite of Romney’s intent.

Incidents such as this administer evidence that social media have the potential to increase the number of world exposed to political content and potentially galvanized for causes and candidays. It likewise raises comes to that it may not assist improve our level of political discourse and civility.

What is the probcapacity of a Chicback Cubs World Series Championship in 2015?

—Brian Bernardoni ’91, Justice

Tright here are multiple techniques to calculate a probability. A timeless method is equally likely outcomes. There are 30 teams in Major Organization Basesphere, and also if each has the very same opportunity of winning the World Series, the probability is one split by 30. This calculation outcomes in .033 or a 3.3 percent opportunity.

Somewhat concerned this technique is loved one frequency. Since the Cubs have not won the World Series considering that 1908, the family member frequency is less than 1 out of 100. At a more technological level the often misapplied law of averages is better taken as annually starts anew. Still less than 1 percent.

As of beforehand morning May 25, the Cubs had actually the 9th ideal document in baseround, 3.5 games behind the Cardinals. Sorry—my prejudice is emerging! Based on this document and also a sophisticated analysis/prognosis, the consensus of the Sports Book in Las Vegas is a 7.7 percent chance. Follow the money for the many realistic estimate.
