what is quark?

-
A quark is a type of elementary particle and a fundamental constituent of matter. Quarks combine to form composite particles called hadrons, the most stable of which are protons and neutrons, the components of atomic nuclei.

                                               Quark, any member of a group of elementary subatomic particles that interact by means of the strong force and are believed to be among the fundamental constituents of matter. Quarks associate with one another via the strong force to make up protons and neutrons, in much the same way that the latter particles combine in various proportions to make up atomic nuclei. There are six types, or flavours, of quarks that differ from one another in their mass and charge characteristics. These six quark flavours can be grouped in three pairs: up and down, charm and strange, and top and bottom. Quarks appear to be true elementary particles; that is, they have no apparent structure and cannot be resolved into something smaller. In addition, however, quarks always seem to occur in combination with other quarks or with antiquarks, their antiparticles, to form all hadrons—the so-called strongly interacting particles that encompass both baryons and mesons.

    This note gave me an idea about quark and sub atomic particles its useful

CONVEX LENS Convex lens is thicker at the centre and thinner at the edges. An optical lens is generally made up of two spherical surfaces. If those surfaces are bent outwards, the lens is called a  biconvex lens  or simply convex lens. These type of lenses can converge a beam of light coming from outside and focus it to a point on the other side. This point is known as the focus and the distance between the centre of the lens to the focus is called the  focal length of convex lens.  However, if one of the surfaces is flat and the other convex, then it is called a  plano-convex lens. Difference between convex and concave lens: There is another type of lens known as concave lens. The major differences between the two are: CONVEX CONCAVE This lens converges a straight beam of light. This lens diverges a straight beam of light. This lens is thicker at the centre and gets thinner as we move towards the edges. This lens is thinner at the centre and gets thicke

wax fire

-
A  wax fire  is created when melted or boiling  wax  is doused in water.   In the case of wax melted down, only the top surface has access to oxygen, so the fire progresses slowly. When water is added to the wax, two things happen. Firstly, the water — being denser than wax — sinks to the bottom of the container. Secondly, as burning wax quickly reaches a temperature of well over 200 degrees C, the water instantly vapourises. When water changes from a liquid to a gas, there is more than a thousand-fold increase in volume. The water expands violently, and throws the hot wax layer above it into the air as small droplets. The wax now has a much bigger surface area exposed to oxygen so combustion takes place very quickly.

1.Almond milk Almond milk is easier to prepare. It also helps in weight management and keeps bones healthy. Unlike the processed milk available in stores, the home-made variant doesn't require refrigeration and is void of chemicals and preservatives. 2.Almond shake Mix almonds with ice, milk, sugar and yogurt in a blender and serve chilled. The almond shake is very high on nutritional value and helps in strengthening of bones and is also rich in vitamins. 3. Chopped almonds in breakfast 4. As a face scrub Add skin soothing agents, like honey, lemon or oatmeal, to the pulp of almond and apply on your skin. Almond nuts are very effective in enhancing skin's natural glow. 5.In place of junk food Almond can be a wonderful and a healthy substitute for junk food
