The science of how Messi keeps the ball close to himself photo credit: ZaleDesigns Messi is a magician with the ball at his feet. He's in my opinion the best player in the sense that he can control the ball so well, runs so fast with the ball & changes the direction at full speed like it's a walk in the park. For starters he started playing very early (at 3) which is crucial if you want to be a good player. In that aspect, he's God gifted as he had dribble skills which is genetic in my opinion. Height He is short which means a low center of gravity so it's difficult to push him off the ball. That's why we see that anyone rarely can topple him down, instead players much larger than him lose possession to him. So his short height suits his style of play & is a blessing in disguise. Change of pace Messi changes his pace really well. He starts slow and runs directly at the defender which means the defender has to stop & focus on him. When he reac...
Chemistry - Acids, Bases, and Salts Introduction We taste food sour and bitter, it is only because of presence of acids and bases respectively. Litmus Solution Litmus, which is extracted from lichen, has purple color (see the image given below), but the condition is when it is neither acidic nor basic, i.e. neutral. Litmus basically is a plant belongs to Thallophyta, and in chemical experiment, it is commonly used as an indicator. The substances, which odor changes in acidic or basic media, are known as olfactory indicators. Acid or Base in a Water Solution The hydrogen ions in HCl are produced because of the presence of water. Secondly, the separation of H + ion from the HCl molecules cannot be done in the absence of water. The chemical formula is illustrated below HCl + H 2 O → H 3 O + + Cl – Furthermore, hydrogen ions cannot exist alone, but they can exist in presence of water molecules. Therefore, hydrogen ions are shown as H + (aq) or hydronium i...
