![]() ![]() The sand or other substances were organized into different structures characterized by geometric shapes typical of the frequency of the vibration emitted by the oscillator. ![]() Jenny put sand, dust and fluids on a metal plate connected to an oscillator which could produce a broad spectrum of frequencies. In 1967 Hans Jenny, a follower of the anthroposophical doctrine of Rudolf Steiner, published two volumes entitled Kymatic (19), in which, repeating Chladni's experiments, he claimed the existence of a subtle power based on the normal, symmetrical images made by sound waves. The figures thus obtained (with the aid of a violin bow that rubbed perpendicularly along the edge of smooth plates covered with fine sand) are still designated by the name of "Chladni figures". This provided an important contribution to the understanding of acoustic phenomena and the functioning of musical instruments. Įxperiments of this kind, similar to those carried out earlier by Galileo Galilei around 1630 and by Robert Hooke in 1680, were later perfected by Chladni, who introduced them systematically in 1787 in his book Entdeckungen über die Theorie des Klanges (Discoveries on the theory of sound). The normal modes of vibration, and the pattern of nodal lines associated with each of these, are completely determined, for a surface with homogeneous mechanical characteristics, from the geometric shape of the surface and by the way in which the surface is constrained. The points form a pattern of lines, known as "nodal lines of the vibration mode". The powder moves due to the vibration and accumulates progressively in points of the surface corresponding to the sound vibration. The German musician and physicist Ernst Chladni noticed in the eighteenth century that the modes of vibration of a membrane or a plate can be observed by sprinkling the vibrating surface with a fine dust (e.g., lycopodium powder, flour or fine sand). Hooke ran a bow (musical) along the edge of a glass plate covered with flour, and saw the nodal patterns emerge. On July 8, 1680, Robert Hooke was able to see the nodal patterns associated with the modes of vibration of glass plates. Other examples include the Chladni Plate and the so-called cymascope. The apparatus employed can be simple, such as the Chinese spouting bowl, in which copper handles are rubbed and cause the copper bottom elements to vibrate. Different patterns emerge in the excitatory medium depending on the geometry of the plate and the driving frequency. Typically the surface of a plate, diaphragm, or membrane is vibrated, and regions of maximum and minimum displacement are made visible in a thin coating of particles, paste, or liquid. The term was coined by the Swiss physician Hans Jenny (1904-1972). From the film Inner Worlds Outer Worlds.Ĭymatics (from Ancient Greek: κῦμα, romanized: kyma, lit.'wave') is a subset of modal vibrational phenomena. A demonstration of sand forming cymatic patterns on a metal plate. ![]()

First key is that the flour / cornstarch / egg mixutre is a WET batter. I do agree the directions were a tad confusing, however after reading reviews I made some adjustments and it turned out perfect. If I had to rate this on taste alone, I would give 5 stars. ![]() This is the best orange chicken that I have tasted. Also you may want to cut back on the crushed chili pepper! And definitely double up on your sauce! I will definitely be making the sauce again. The real secret to this recipe is that true orange taste from the sauce. this recipe was time consuming and the unclear instructions. ![]() It came out great! The only bad point I had. Also I used about 1/3 of an orange for the zest. This will help enhance the flavor of the sauce. For the sauce itself, I substituted the water and vinegar with orange juice. Then I put the chicken in the deep fryer. I put the chicken in the egg mixture first and then took each piece out and coated it with cornstarch only. I deviated slightly from the recipe based on previous comments. This recipe has a true orange zest! I must agree with others reviewers that the instructions are not too clear. It actually taste better than Panda Express. It does not taste like Panda Express' orange chicken. It is a very good recipe for orange chicken. In a small bowl, stir together the water and cornstarch, then add it to the wok and stir until sauce has thickened.Add cooked chicken, stirring until well mixed.Now, add the rice wine and the soy sauce mixture you set aside above.Add 1 tablespoon oil, the gingerroot, garlic, crushed red chili pepper flakes and green onions and stir-fry for just a few seconds until fragrant.Clean wok and heat 15 seconds over high heat.In a small bowl, combine the soy sauce, orange juice, brown sugar and orange zest.Remove chicken from oil with slotted spoon and drain on paper towels set aside.Add chicken to wok in small batches and fry for 3 to 4 minutes or until golden brown.Dip chicken pieces into egg mixture, then into the flour mixture, shaking off any excess.Heat oil for deep-frying in wok or deep-fryer to 375 degrees.In a medium bowl, stir together 1/2 cup of the cornstarch and the flour.In a medium bowl, stir egg, salt, pepper and 1 tablespoon oil and mix well, set aside.Place chicken pieces in a large bowl, set aside. ![]() ![]() On September 13, 2021, Intuit confirmed it would acquire Mailchimp for approximately $12 billion in cash and stock. Acquisition by Intuit Īfter turning down repeated acquisition offers for 20 years, Bloomberg reported on August 31, 2021, that Mailchimp was talking with Intuit about being acquired. With founders Armstrong and Chestnut starting the company without outside funding or plans to go public, and never bringing on any outside investors thereafter, Mailchimp is considered to be an example of a successfully bootstrapped startup. The magazine has a readership of 100,000 readers in more than 26 countries. As part of this, Mailchimp acquired the London-based media and magazine company Courier Media, in March 2020, with the stated goal of international growth. Mailchimp later announced its plans to shift from mail distribution to offering "a full marketing platform aimed at smaller organizations." This shift includes allowing customers to record and track customer leads within the platform, build landing pages and websites, and run ad retargeting advertisements on Facebook and Instagram. In February 2019, Mailchimp acquired LemonStand, a smaller competitor. In August 2017, it was reported that Mailchimp would be opening offices in Brooklyn and Oakland, California. ![]() In February 2017, the company was named one of Fast Company's Most Innovative Companies of 2017. ![]() In 2016, Mailchimp was ranked No. 7 on the Forbes Cloud 100 list. According to the statistics, more than 600 million emails are sent through the platform every two days. By June 2014, it was sending over 10 billion emails per month on behalf of its users. Within a year, its user base had grown from 85,000 to 450,000. Mailchimp began as a paid service and added a freemium option in 2009. The platform was named after one of their most popular e-greetings card characters, and earned a few thousand dollars a month. "Mailchimp" is the trade name of its operator, Rocket Science Group, an American company founded in 2001 by Ben Chestnut and Mark Armstrong, with Dan Kurzius joining at a later date. Mailchimp is a marketing automation and email marketing platform. ![]() ![]() ![]() Synchrotron radiation is emitted by electrons or positrons travelling at near light speed in a circular storage ring. In recent years synchrotron facilities have become widely used as preferred sources for x-ray diffraction measurements. (The energy E of a x-ray photon and its wavelength is related by the equation E = hc/ l, where h is Planck's constant and c the speed of light) (check out this neat animated lecture on x-ray production) Common targets used in x-ray tubes include Cu and Mo, which emit 8 keV and 14 keV x-rays with corresponding wavelengths of 1.54 Å and 0.8 Å, respectively. When a free electron fills the shell, a x-ray photon with energy characteristic of the target material is emitted. The high energy electrons also eject inner shell electrons in atoms through the ionization process. As electrons collide with atoms in the target and slow down, a continuous spectrum of x-rays are emitted, which are termed Bremsstrahlung radiation. In a x-ray tube, which is the primary x-ray source used in laboratory x-ray instruments, x-rays are generated when a focused electron beam accelerated across a high voltage field bombards a stationary or rotating solid target. X-rays are produced generally by either x-ray tubes or synchrotron radiation. The energetic x-rays can penetrate deep into the materials and provide information about the bulk structure. Because the wavelength of x-rays is comparable to the size of atoms, they are ideally suited for probing the structural arrangement of atoms and molecules in a wide range of materials. For diffraction applications, only short wavelength x-rays (hard x-rays) in the range of a few angstroms to 0.1 angstrom (1 keV - 120 keV) are used. X-rays are electromagnetic radiation with typical photon energies in the range of 100 eV - 100 keV.
