In the past, sour cream was made by skimming the cream off the top of milk and allowing it to sit at a moderate temperature until it turned sour. It's also a great ingredient to use in baking! How Do You Make Sour Cream? Sour cream is often used as a condiment for soup, chili and taco bowls. Regular sour cream is a dairy product which has been exposed to certain types of lactic acid bacteria causing it to ferment and turn sour and become thick.

Harder to dispel, however, are questions the management shake-up raises about whether the company's co-chairmen and co-chief executives, Weill and Reed, have the ability to groom their successors. Citigroup officials deny anything so violent occurred. Tensions between Citigroup employees has run so high that rumors have circulated that in recent weeks a fistfight broke out between a top manager who had come from Salomon Smith Barney and another who had come from Citibank. It comes just a couple weeks after the president was ousted at BankAmerica Corp., the newly merged institution that combined Bank of America of San Francisco with NationsBank of Charlotte. The Citigroup shake-up is the latest example of the problems of trying to merge giant companies, which often have distinct characters in general and very large egos among top management in particular. "He was thoughtful and always willing to spend time explaining."Ĭitigroup's stock fell as much as 4.7 percent yesterday before recovering to close down 87.5 cents at $46.25. "We all wanted to hate him, but he turned out to be a real quality guy," said a Salomon investment banker. Yesterday, when Dimon walked onto the Salomon Smith Barney trading floor, nearly 1,000 traders stood up and gave him a standing ovation. In the end, Dimon resigned and Maughan was stripped of most of his management duties. Reed warned Dimon, 42, and Maughan, 50, to work out their differences or face a loss of power. Sources said Weill and co-chairman and co-chief executive John S. Several sources said that Dimon's relationship with Deryck Maughan, his co-chief executive at Salomon Smith Barney, the Travelers securities arm, deteriorated in recent months as Travelers digested its 1997 acquisition of Salomon Brothers.

If you’re having trouble with naps, you might be interested in helping your baby nap.Īlthough many babies can go all night without a single feeding, in my experience, some do better with one feeding after 4 or 5 a.m. Wake windows at this age are typically 3-4 hours at a time. Your 11-month-old should be taking 2 naps per day for a total of 2-3 hours per day plus 11-12 hours at night. ![]() It makes me think my older son would have gone back to two naps, too, had I given him more time to try. My younger son seemed to start to transition to one nap around the same time, but went back to two naps within a week or two and continued taking two naps until 15 or 16 months. The average age to transition to one nap is 15-18 months. Most babies get very very overtired and sleep can spiral out of control, so I always recommend keeping two naps as long as possible. My eldest son did transition to one nap one week before his first birthday, so it was in the 11th month that I started seeing his morning nap get later and later. A very small percentage transition to one nap as early as 10 months, but not many, so assume 2 naps unless you are certain. Babies this age take 2 naps for a total of 2 to 2 1/2 hours per day plus 11-12 hours at night.

The primary colors are the basis for all other colors. Selecting a region changes the language and/or content on primary colors are red, yellow, and blue. Keep a color wheel handy to determine what the best complementary colors are for your next project. If you choose a color on the opposite side of the wheel, it gives whatever you color the most substantial contrast while it remains pleasing to the eye. This is what’s called a complementary color scheme. And then picking your primary color that is opposite on the color wheel,” says Newman. “With illustration, you can definitely get away with taking the analogous color palette for your secondary colors. Luckily, digital illustration doesn’t have the same properties as traditional art, so it allows some flexibility in how you use the color palette you choose. For instance, yellow-green, yellow, and yellow-red are all vivid colors, each with their complexity, but when used together in a painting, it can look like a primary yellow. “There are mixed opinions with this approach because it’s very easy to have a calming color palette, but then you also have very low contrast, and all the colors blend together,” Newman says. This is a simple method to develop a color system, but it’s not without its flaws. You’ll need to have the proper contrast, so most illustrators choose one dominant color, along with a second supporting color and a third color to be used as an accent or highlight. These are the four basic colors of ink used in printing color images.ĭo you want colors that flatter each other? Choose colors that are located right next to each other on the color wheel. However, if printing is your ultimate goal, digital artists and designers can use, or convert files to, CMYK (Cyan, Magenta, Yellow, and Black). The light source of a monitor or screen can create any color you can imagine with the combination of different shades of red, green, and blue. Typically, print artists use the RYB color model, as it’s best suited to illustrating the correlation between physical colors in inks and paints in the color mixing process.įor designers or artists who work in the digital medium, the RGB color palette is most typically used, as those colors are found in the photoreceptors of the eyes. There are two types of wheels: one based on the primary colors of RYB (red, yellow, and blue) and one based in RGB color (red, green, and blue). Arranged in the order the colors appear in the light spectrum (red, orange, yellow, green, blue, indigo, and violet), Sir Isaac Newton created the first color wheel in 1666. It’s the standard tool for viewing and understanding color combinations. The color wheel represents all visible colors. ![]() Steam default screenshot folder11/24/2023 ![]() ![]() If you don’t know where Steam screenshots are saved, you can follow the steps above to find the Steam screenshot folder and check out your Steam screenshots.

In general, quantum entanglement describes a nonclassical physical state, in which atoms in a group show correlated measurement results, even though each individual atom behaves like the random toss of a coin. This is where Vuletic and his group have shown that quantum entanglement may help. A second, very stable laser, with a frequency close to that of the atoms' vibrations, is sent to probe the atomic oscillation and thereby keep track of time.Īnd yet, the Standard Quantum Limit is still at work, meaning there is still some uncertainty, even among thousands of atoms, regarding their exact individual frequencies. A typical atomic clock does this by first using a system of lasers to corral a gas of ultracooled atoms into a trap formed by a laser. This is why today's atomic clocks are designed to measure a gas composed of thousands of the same type of atom, in order to get an estimate of their average oscillations. "When you increase the number of atoms, the average given by all these atoms goes toward something that gives the correct value," says Colombo. This limitation is what physicists refer to as the Standard Quantum Limit. But at that scale, an atom is so small that it behaves according to the mysterious rules of quantum mechanics: When measured, it behaves like a flipped coin that only when averaged over many flips gives the correct probabilities. To keep perfect time, clocks would ideally track the oscillations of a single atom. Furthermore, one cesium atom will oscillate at exactly the same frequency as another cesium atom. Today, vibrations in atoms are the most stable periodic events that scientists can observe. Since humans began tracking the passage of time, they have done so using periodic phenomena, such as the motion of the sun across the sky. The paper's other co-authors from MIT are Simone Colombo, Chi Shu, Albert Adiyatullin, Zeyang Li, Enrique Mendez, Boris Braverman, Akio Kawasaki, Saisuke Akamatsu, Yanhong Xiao, and Vladan Vuletic, the Lester Wolfe Professor of Physics. If state-of-the-art atomic clocks were adapted to measure entangled atoms the way the MIT team's setup does, their timing would improve such that, over the entire age of the universe, the clocks would be less than 100 milliseconds off. ![]() "Entanglement-enhanced optical atomic clocks will have the potential to reach a better precision in one second than current state-of-the-art optical clocks," says lead author Edwin Pedrozo-Peñafiel, a postdoc in MIT's Research Laboratory of Electronics. The new setup can achieve the same precision four times faster than clocks without entanglement. The atoms are correlated in a way that is impossible according to the laws of classical physics, and that allows the scientists to measure the atoms' vibrations more accurately. The researchers report in the journal Nature that they have built an atomic clock that measures not a cloud of randomly oscillating atoms, as state-of-the-art designs measure now, but instead atoms that have been quantumly entangled. Now a new kind of atomic clock designed by MIT physicists may enable scientists explore such questions and possibly reveal new physics. With better atomic clocks, scientists could also start to answer some mind-bending questions, such as what effect gravity might have on the passage of time and whether time itself changes as the universe ages. If atomic clocks could more accurately measure atomic vibrations, they would be sensitive enough to detect phenomena such as dark matter and gravitational waves. ![]() AuthorWrite something about yourself.
