Visual science, directly proportional. One of the characteristic attributes of a circle is that its diameter and circumference have a proportional relationship. Meaning that no matter the size of a circle, the proportional relationship or ratio between its circumference and diameter is always the same.

Visual science, force (1/40) Hoping on a diving board your weight applies a load, to produce a deflection; this deflection gets stored in the board that's strain energy. The board bends to the lowest point, the board pauses it's at static equilibrium, this strain energy is then released and converting back into kinetic as the board moves up you are sent up with the board. You and the board travel upwards, by way of your momentum that has been conveyed to you by your kinetic energy. You ascend up in the air due to your momentum, until your kinetic energy plummets becoming gravitational potential energy, producing the driving force to attract you back down and into the water. The board its self could only travel so far up until its stiffness returned it, bringing it back down this time not so far, it moves up and down and so on vibrating in place becoming virtually still again.

Visual science, divided (2/40) Dividing cakes has never been to tricky, but larger divisions can feel like there's a cow bell going off inside your head, here's a little trick, dividing large numbers by five is in fact pretty simple! First multiply your number by two and next move the decimal point back one place.

Visual science, heat transferred (3/40) When you press your body up against another body outside in the cold, the rate of heat lost to the environment slows down because surface area exposed to the environment is less. If one is much warmer than the other, some of the heat lost from the warmer person will be harvested by the colder person until the two are roughly at an equal temperature, at that point heat losses from each person individually is lower.

Visual science, resistance (4/40) Resistance is the barrier put up by an object to the flow of current through it. When an eel presses its chin against its victim to deliver a shock, electricity flows through the eel where the eel provides some resistance and on to the target, but water provides less resistance and carries electricity with ease, so if the eel's still submerged when it delivers the shock, the charge dissipates. An electric current flows when electrons are moving through a conductor, a more common place type of conductor would be an electric wire. The moving electrons can collide with the ions in the metal, this makes it more difficult for the current to flow, and causes resistance.

Visual science, delta (Δ) (5/40) Delta necessarily refers to, “a change in”. Δx expresses a change in x. For instance winds bring changes in the weather, such as pouring rain or sunny skies.

Visual science, (G)ravitational constant (6/40) Mass is inextricably linked to gravity, so that all objects no matter how tiny have a proportional gravitational pull on each other. A team of researchers measured the smallest gravitational pull so far, it was equivalent to around the mass of a ladybug. There setup had no more “give” downward but it can freely spin horizontally, they did this by placing a larger weight next to those small one's on the ends of the beam, the two weights will attract each other and turn the rod ever so slightly and this force of gravity can be measured.

Visual science, half (7/40) Halves can be very useful indeed, let's look at an example. Elements can be made of different isotopes, isotopes are the atoms that have the same number of electrons and protons but a different number of neutrons. Sometimes isotopes can be stable and happy these elements are the one's we see in nature, sometimes isotopes are unstable, they are called radioactive isotopes. The half-life of an isotope is the time on average that is taken for half of the atoms to decay. Very precise dating of objects can be calculated given the known half-life for that element.

Visual science, half (8/40) The bath is half full! Ok that's it for today! If you want to hang about we are looking a little closer at baths, and thinking about extrapolation and other fun facts! When an object displaces a quantity of water that is equal to its own weight, the buoyant force acting will be equal to gravity at which point the object will float, however, if the object weighs more than the water it's displacing, the buoyant force acting will be less than gravity, so it will sink.

Visual science, minus (9/40) Minus, to take away have less of a quantity by means of subtraction. When it's minus five degrees in the great outdoors, it's five below zero or five degrees less than zero. So when you talk about negative numbers, whether that's in relation to temperature or your finances, the adjective minus always applies.

Visual science, current (10/40) Electric current is classed as the flow of electrons. Electricity is found in every walk of life, even within our body. Cells are specialized to conduct electricity contained within our bodies elements like magnesium, potassium, calcium and sodium, have a particular electrical charge. Nearly all of our cells have the ability to use these charged elements called ions to produce electricity.
