ADENOVIRUS: Adenoviruses (AdV) are large naked viruses with characteristic fibres projecting from each vertex of their icosahedral capsids. Genome is double-stranded DNA. Adenoviruses tend to cause respiratory disease. Also used as vectors and for vaccines. This is a new version with more and brighter virions.
Coloured Adenoviruses 4K Animation
Adenoviruses (AdV) are large naked viruses with characteristic fibres projecting from each vertex of their icosahedral capsids. Genome is double-stranded DNA. Adenoviruses tend to cause respiratory disease. A chimpanzee-derived adenovirus is used as a vector in the new Oxford vaccine against the coronavirus, (ChAdOx1 nCoV-19 vaccine)
Supercavitating Torpedo, an Underwater Missile
Supercavitating, rocket-powered torpedo (red) travelling through the sea in a bubble of its own creation. The flattened nose creates areas of very low pressure that result in bubbles (cavities). When these merge into a bubble that encloses the projectile, it is called supercavitation. Gas is expelled at the nose to help with the bubble creation. The cavity (containing water vapour) dramatically reduces the drag on the torpedo, so that it flies like a missile, many times faster than a conventional torpedo.

Graphene is an allotrope of carbon consisting of flat sheets of hexagonally arranged carbon atoms. When stacked in layers, graphene makes graphite, of pencil fame. Graphene is a very good electrical conductor because electrons easily travel along the plane of the sheet. May be useful in batteries, according to recent news items.

My shed, where I do all my writing and illustrating, looking magical in a Canberra sunset from a couple of nights ago. You might just glimpse a Hills Hoist in the foreground.Circular Waves Interfering (Rose Gold Metal Style)
Circular waves radiate out from two point-sources creating an interference pattern as they superimpose on each other. The waves sum together producing higher peaks and deeper toughs at some points, whilst cancelling each other out at other points. This is done in the same rose gold metal style as the two-slit experiment. You can licence it here.
Double Slit Experiment, 4K Animation in Rose Gold
Thomas Young's classic double-slit experiment. Created and rendered in Blender in pale rose gold. Composited in DaVinci Resolve. Plane waves hit a screen with two gaps. The gaps act as new wave sources, creating two sets of circular waves radiating outwards. These two new waves create an interference pattern as they superimpose on each other. The waves sum together producing higher peaks and deeper troughs at some points (constructive interference), whilst cancelling each other out at other points (destructive interference). Weird quantum stuff happens with light in the double-slit experiment... Licence for academic and commercial use.
Super Cavity: Bullets Through Water & Supersonic Subs
Projectile (red) travelling through the water in a bubble of its own creation. The flattened nose creates areas of very low pressure that result in bubbles (cavities). When these merge into a bubble that encloses the projectile, it is called supercavitation. Larger objects can use supercavitation but they must augment the pressure drop with gas expelled at the nose (e.g. rocket-powered torpedos).
BUY THIS SUPERCAVITATION ANIMATION.The counterintuitive phenomenon is created when a projectile tears a tunnel through the water. This tunnel or super-cavity reduces drag on the sides of the projectile and it races along.

Doppler Shift Animation
Another in my series of wave animations. This is also in UHD (4K) and you can watch it at full size from this blog by clicking the video expand button.
Generalised animation of the increase in frequency observed in waves emitted from an approaching source (or conversely a decrease in frequency in waves emitted from a receding source). This Doppler Shift happens in sound waves (e.g. a siren of an approaching emergency vehicle or the change in pitch of a passing car engine) and in light waves (the red Doppler shift of a receding star or the blue Doppler shift of an approaching star, redshift and blueshift).
This animation uses a ball as the wave source. As the ball moves from left to right it emits wave-fronts that continue to radiate out from their position of origin. The ball moves on and creates a new point of origin for the next wavefront and so on. In this way, the waves bunch together at the front of the ball and spread out behind. Similar to a jet plane approaching the speed of sound and radiating sound waves. In the case of light waves then the higher frequency at the front yields a bluer light (blue shift), while behind the light source (e.g. a star) the light is stretched out, lengthening the frequency, creating a redshift. Licence this Doppler animation.
Mach 1, Mach 2. Two New Animations of waves
Generalised animation of a moving wave source travelling at the same speed as the waves. An example would be an aircraft travelling at the speed of sound (Mach 1). The waves expand outwards at the same speed as the object moves and concertina together at the front of the object. This assembling wall of compression that cannot escape is called the sound barrier in the case of aircraft. If the plane exceeds the speed of sound it breaks through the sound barrier and becomes supersonic creating a conical shock wave (Mach cone), where the wavefronts trail the object. Licence this animation.
Generalised animation of a moving wave source travelling at twice the speed as the waves. An example would be an aircraft travelling at Mach 2. The waves expand outwards but lag behind the object creating a conical shock wave (Mach cone), or a wake in the case of a ship creating waves in the ocean. Licence this animation.
