INPUT ARTICLE: Article: In quantum mechanics, the quantum of action is the Planck constant, usually denoted as h. Likewise, for interacting subatomic particles, the quantum of angular momentum is the reduced Planck constant (the Planck constant divided by 2π) denoted by ħ and called "h-bar". The value of the Planck constant is extremely small, its units are those of angular momentum, and the notion of action is the more general mathematical concept. As the name quantum mechanics implies, certain physical quantities such as angular momentum can change only in discrete amounts, and not in a continuous (cf. analog) way.  For example, the angular momentum of an electron bound to an atom or molecule is quantized and can only have values that are multiples of the reduced Planck constant. This quantization gives rise to electron orbitals of a series of integer primary quantum number. In contrast, the angular momentum of a nearby unbound electron is not quantized. The Planck constant also plays a role in the quantum theory of light, where the quantum of light is the photon and where matter and energy interact via the atomic electron transition or "quantum leap" of the bound electron. The units of the Planck constant can also be viewed as energy times time. For example, in the subject area of particle physics, the notion of virtual particles are messy particles that spontaneously appear out of the vacuum for a tiny fraction of a section and play a role in a particle interaction. The limit to the lifetime of these virtual particles is the energy (mass) of the particle times that lifetime. Quantum mechanics is a large subject area but every part of its mathematics involves the Planck constant. Massy particles go through a classical-to-quantum transition. Even though the free electron displays some quantum properties (such as spin), as the unbound electron approaches the atom and slows down (perhaps by emitting photons), it undergoes a transition from classical to quantum behavior as its energy goes below the ionization energy. The electron is then bound to the atom and its angular momentum with respect to the atomic nucleus is restricted to quantized values of the orbitals it can occupy. The transition is sudden. One might compare this transition with that of a mechanical system that changes from displaying unstable to stable behavior or from displaying simple to chaotic behavior, or even a rocket ship slowing and going below escape velocity and entering orbit around some star or other celestial object. In contrast photons (which are massless) do not go through such a transition: photons just travel through space unchanged until they interact with other particles and then disappear. As you look into the night sky, the photons from some star traveled through light years of space unchanged then interacted with an electron in a molecule of your retina, transferred its energy and then otherwise disappeared.

SUMMARY: Start with learning about the physical significance of the Planck constant. Learn about massy particles.

In one sentence, describe what the following article is about: Before you begin to remove a dried paint stain with chemicals, you should attempt to remove as much dried paint as you can manually. Depending on the amount of paint that is on the fabric, you may be able to scrape some off with a blunt scraper like a putty knife. You may also be able to use a brass wire brush or a stiff nylon brush to remove some of the dried paint. Be careful not to rip the fabric as you try to remove the paint. If none will come off, move on to the next step. Once you have removed as much excess paint as you can by scraping and brushing, you will need to soften the remaining paint with one of several alcohol-based solvents. Chances are you already have one of these products at home. Apply a small amount directly to the paint to begin loosening it.  Rubbing alcohol, turpentine, and mineral spirits are all effective solvents for acrylic paint. If you don't have any of these solvents on hand, you can try an acetone-based nail polish remover or even hairspray (as long as it contains alcohol). If none of these products work for you, try visiting your local home improvement store and buy a cleaning product that is specifically designed for removing the type of paint you are dealing with. For stubborn stains, you may have to let the solvent sit on the fabric for a while before you start scrubbing. Solvents are very harsh, so be careful with delicate fabrics. Acetone will damage certain fabrics, among them, those made of acetate or triacetate. Natural fibers like silk and wool are also easily damaged, so always test the solvent on a hidden area like an inside seam before using it. If your garment cannot be treated with solvents, take it to a dry cleaner to be professionally cleaned. Once the paint molecules begin to break down from the solvent and soften, scrub as much of the paint away as you can. Use a brush with stiff bristles for the best results. Once you've gotten most of the paint out, you can move the garment to the sink and continue scrubbing it with detergent and cold water. After you have finished hand-washing the stain, put your clothes in the washing machine and wash them in cold water with plenty of detergent. Remember to avoid applying any kind of heat to your clothing unless you are sure that the stain is gone.
Summary: Scrape off as much paint as you can. Apply a solvent. Scrub the stain. Machine wash your clothes.

If there are no rules limiting how far you can go when playing this game, it's a good idea to set some personal limits with the person you'll be sharing your 7 minutes in heaven with. If you don't, the other player might misinterpret the signals you are setting and go too far.  You might say something like, "Can we just talk?" or "Let's talk first. I might be OK with a kiss, but I don't want to rush into it." You could also establish a firm boundary by saying, "Kissing is OK, but I'm not OK with other touching." Sometimes something will make you feel uncomfortable without you knowing it beforehand. When this happens, you should use straightforward language to tell the other player that you feel uncomfortable and want to stop.  For example, if you are touched in a way you don't like, you could say, "No. I don't want to be touched there." It can be difficult telling someone "No," but if you don't, things might go farther than you intended. You should never take part in something that makes you feel uncomfortable. This includes things like hand-holding, petting, or other kinds of touches that might exceed the personal boundaries of the other player. This way, you don't accidentally violate someone's boundaries without knowing. It only takes a quick second to ask, "Is it OK if I hold your hand?" or "Is it alright for me to touch you like this?"

One-sentence summary -- Set clear limits before playing. Voice discomfort as soon as it happens. Ask the other player before trying something new.

INPUT ARTICLE: Article: Holding events in the office will allow employees to discuss their work with each other, get to know other employees in different departments, and exchange their views and perspectives on their roles.  A study has shown that workplace relations play a crucial role in employee happiness; even more than employee/boss relations. As well, individual self-esteem will be boosted when employees hear about themselves in a friendly, positive light from their peers and co-workers. Keep in mind that many employees are more receptive to social events initiated by their co-workers, rather than by management. This will encourage cross-workplace ties among your employees and allow them to get to know each other outside of the office setting. A few minutes of the meeting, perhaps at the start, can be devoted to light-hearted conversations or listening to someone’s personal experience. This will help your employees look forward to meetings and stay engaged. Sometimes, small issues such as routine maintenance of common areas, or even the coffee machine breaking down can lead to distraction from the main focus and work of your employees. Address these smaller issues and promote smooth running of the office to limit your employee’s distractions and ensure they are working in a well kept, well run, and engaging space.

SUMMARY:
Organize office events, get togethers, and parties. Promote the office carpool and weekly office lunches. Start each meeting with informal conversation or small talk. Keep the office clean and well maintained.
