Mistakes in SVG Constructive Mistakes in SVG: I was trying to code a Bishop’s mitre in SVG, but I made a mistake in the code... however, with art, mistakes are serendipitous and an impetus to further creativity. So I ended up with this creepy-looking gravestone instead. You can code HTML-5 game graphics in SVG, and I always love creepy graveyards in games. Requiēscat in Pāce Figure 1:   The resulting Gravestone image. Figure 2:   What the image looks like when exported as a PNG. You can locate the source code of this gravestone image at my Codepen Account. Figure 3: There is usually a graveyard in The Legend of Zelda titles! You c...

The Naming of Sets in Set Theory Figure 1:   I drew this set-naming italic character in SVG.  You may view the code of this image at my Codepen Account . Figure 2: What the SVG image looks like when exported as a PNG. [1] In Set Theory - which underpins so much of computing mathematics - we conventionally name sets with capital italic letters. In computer science, a name such as: A , would be termed an: ‘identifier’ . In the below example, we shall use the capital italic character: R so as to name the members of the set of Radix-ten [2] integers. Figure 3: “ A SQUARE-ROOT SIGN   This sign is from radix (Latin for root) and was first used by Leonardo da Pisa in 1220.  Today’s √ sign, which may be a distortion of the letter “r”, is sixteenth-century German.” [3] An Example ...

Lightbulb Unlit Final Figure 1: a lightbulb that I drew in SVG. In Computer Science Courses, an unlit lightbulb is very often used to represent the Boolean Value, False. One may say that - as regards the above lightbulb - that it represents the Boolean Equation: S = 0 You may view the code for this lightbulb on my CodePen account: Unlit Lightbulb SVG Code.

Figure 1:  An ectopic pregnancy. In medicine, the pathological term, 'ectopia,' is a noun that denotes an organ's or other body part's being in the wrong place. 'Ectopic' is the adjectival form of 'ectopia.' An ectopic pregnancy, for instance, occurs whenever the embryo implants itself outside of the womb. ἐκ or 'ek' is an Ancient-Greek preposition that means, 'outside of.' ὁ τόπος or 'ho tópos' is an Ancient-Greek noun that means 'place,' 'location.'

In Ancient Greek, the verb,  κινεῶ or 'kineȭ;' κινῶ or 'kinȭ,' means 'I move.' From the above Ancient-Greek verb, we derive the term, 'kinetic energy,' which - in Physics - is 'the energy that an object possesses by virtue of its being in motion .' We also derive the English noun, 'cinema,' from 'kinȭ.' In Ancient Greek, the noun, τὸ κίνημα or 'tò kínēma,' means 'movement.'  A cinema is a device whereby we may watch feature-length films, or 'motion pictures.' In a 'motion picture,' the pictures are said * to move * , hence we also term them 'movies.'

Figure 1:   An NPN resitor. A transistor is a semiconductor device. A semiconductor, let us remember, is a component that can - when needed - both halt and conduct the flow of current. The semiconducting material from which computer transistors is made from is termed 'doped silicon.' The term 'doped' refers to how its purity has been altered - or alloyed - so that it might better conduct and resist real - as opposed to conventional - positive electric current. A positive electric charge occurs whenever an atom is positively ionized, i.e. whenever an atom's number of electrons be fewer than its number of protons; i.e. whenever an atom contains more protons than electrons. To conceptualise this lack or absence of electrons flowing about a silicon resistor in the flow of real positive current, we very often term this absence of electrons "holes" and we conceive of these "holes" flowing about a silicon transistor. Etymology: Th...

I discovered this image on Twitter. Three impossible objects. This must be what trying to assemble an IKEA piece of furniture must be like if you happen to be extremely drunk.

Figure 1:   As a nineties kid, I remember this puppet well. The proper name, 'Otis,' or / ˈ o.tɪs/ means 'nobody.' It is derived from the Ancient-Greek adverb, οὐκ or ‘ouk;’ or  οὐ or ‘ou’, which means ‘not’ and the pronoun, τις or ‘tis;’ which means ‘somebody,’ ‘someone.’ Hence  Οὖτις, or 'O ũtis,' means 'not someone' or 'not somebody' or 'nobody,' 'no-one.'  'O ũtis,' appears in Homer's Odyssey: Outis in the Odyssey Wikipedia Page A a child, I always hated Otis the Aardvark, though! He was no Ed the Duck, that's for sure! Figure 2:   This is what a real entertainer looks like!
