Squashed Records

Visual science, entropy (24/40) The arrow of time! Often considered to be the disorderliness of everything around us, it can also be given as the number of microstates of system under certain conditions.

Visual science, distance (25/40) Distance is the total movement of an object regardless of direction traveled. We can characterize distance as how much ground an object has covered despite its beginning or ending point.

Visual science, equals (26/40) Before the equals symbol was invented, mathematicians would use useful and expressive words as an indication of what was going on. When adding, they used "yields" or "gives". Other earlier symbols for equality included "æ" parallel lines pointing up were also used. These days an increasing number of mathematicians have become skeptical that the equal sign, traditionally used to show exact relations between sets of things, holds up to modern mathematical models. A wave of mathematicians are turning to the idea of category theory, based in understanding the relationships between different objects. This would super seed set theory at dealing with equivalence, as it is more universally applicable to alternate branches of maths.

Visual science, photon (27/40) Quantum objects have a curious nature they can be a particle, like a hockey puck, and some kind of wave, like a wave splashing on the shores. Think of hockey puck that can be in several different places all at one time. But when you spot it with your with measuring instruments, said quantum object is all of a sudden reduced to one spot. This means that molecules atoms electrons even photons , are found to be particles and waves, both at the same time! It is the basic underlying property of the quantum world. In theory, duality is a property not only of atomic and subatomic particles but larger objects exhibit these quality's such as basketballs, planets even humans, although this duality is much more difficult to observe for more sizable articles, that said they have seen this behavior in materials the size of a molecule.

Visual science, time (28/40) The time expended by light traveling towards Earth means that when we look at planets, stars and galaxies, we're actually peering back in time. The light entering our eyes from distant objects set off years, decades or millennia earlier. Due to the finite speed of light we can work out that when you look up at the Sun, you see it as it existed 8 minutes ago!

Visual science, initial speed squared (29/40)

Visual science, speed squared (30/40) Speed the distance covered per time unit, does not account for direction if you drove around the block returning to your original position, you would have a speed the distance divided by the time but your velocity would get recorded as zero since your position didn't change from start and the end of the interval. To square your speed you must multiply its value by its self!

Visual science, mass (31/40) The average mass of an American football player is 112 kg where as the mass of the observable Universe is vastly greater at 10^53kg. Mass is a combination of the total number of atoms, the type of atoms and the density of the atoms in an object irrespective of where it is. It is, in effect, the resistance that a body of matter offers to a change in its speed or position upon application of a force.

Visual science, frequency (32/40) Frequency referred to as the number of waves that pass a fixed place in a given amount of time. So if the time for a wave to pass is 1/2 second, the frequency is 2 per second, 2Hz. The measurement in hertz, abbreviated Hz, is the number of waves passed per second.

Visual science, energy (g)ravitational (33/40) Immediately on leaving the aircraft, the skydivers accelerate downwards due to the force of gravity. A heavy person does not accelerate more than a lighter person when both are freely falling! Because the greater mass offsets the equally greater force. They accelerate downwards, gaining speed second by second. This increase in speed is accompanied by increased air resistance. The air resistance counters the force of gravity. As the skydivers descend, the amount of air resistance goes up more and more until it reaches the magnitude of the force due to gravity. When the air resistance is as large as the gravitational force, a balance is struck, the skydiver stops accelerating. The skydiver has reached a terminal velocity.

Visual science, height (34/40) Height is an expression of vertical distance, either vertical extent how tall or vertical position how high. Where the height of an object is unknown it can be easily found by dropping a small pebble off the top and then perform a calculation using the speed of sound, however this is not always possible but we have been assured that Angel Falls is 979 meters tall making it the world's tallest waterfall.

Visual science, period T (35/40) A time period T is the time taken when one complete cycle of vibration passes a point. As the frequency of a wave increases, the time period T of the wave goes down. The most common unit for measuring period is 'seconds' period is expressed in units of time such as seconds, hours, days or years. The period of orbit for the Earth to go all the way around the Sun is approximately 365 days.
