How a runner can go further in less time at the same speed.

When movement is in a faster time frame, time dilates.

Relativity causes movement in a faster time frame to dilate time, either for an astronaut or for a stimulus response signal in human nervous system. Time dilation is explained below.
Einstein did a thought experiment about a spaceship. An astronaut inside it flashes a pulse of light perpendicularly across the spacecraft, setting off a timer and reflecting back from a mirror to the timer again. The travel time across the width is T seconds read from the timer.’
If the spaceship moves forward at the speed of light, would the travel time T across the spaceship and back be the same as when it was stationary?’
If we could look inside through a porthole using a telescope from Earth, we would see the path of the light pulse illuminating dust particles in the air along a diagonal path to the mirror in its new position, being reflected off the mirror and coming back along another diagonal, completing a dogleg.
Can the light pulse still go across in T? It has three conditions to obey. 1. The diagonal path is further than the path perpendicularly across; 2. It must arrive by the same time T; and 3. It cannot go faster than the speed of light.
It can’t, because to go further along the diagonal in the same time, it would have to go faster. But if it was already at the speed of light and couldn’t go faster. Nor could it arrive after the time the astronaut would observe.
Therefore it would be impossible for the pulse to be seen at the same time. Einstein supposed time would dilate or stretch. If each second lasted longer, it would make sense. We are used to a pendulum beating out constant aliquots of time but at high speeds it would have to beat more slowly and because each second would be longer, the longer distance could be travelled in fewer seconds.
Next in this series it is shown how time dilation for a person in a much faster time frame would cause a higher speed of travel.
My fiction novel Time is Gold, to be published shortly, tells how an athlete exploits metaphysics and wins.


Restrictions on social behaviour could change how we act and think for long after the COVID-19 epidemic ends.

Proxemics is the study of how interpersonal distances and spaces affect human interaction, regulated by body language and communication. Individuals have intimate, personal, social and public zones, at increasing radii. If access to each other’s intimate zone up to 0.50 metres away is denied, intimate interaction would be reduced, affecting particularly relations between family members. Keeping people more than 1.0 metres away would exclude them from the personal zone, with a diminution of correspondence about matters of personal significance, such as observations and opinions. At social distances beyond, out to 4 metres, exchange of acknowledgement, greetings, humorous quips, retorts and peremptory comments are more likely. Further away, in the public zone, information might be broadcast by a speaker, or received by an audience member, without having individual personal content.

Besides reducing transmission of the virus, social distancing will reduce intimacy and personal expression. A role of near-distance interaction is to maintain and build a relationship, with communication of beliefs and negotiation of differences with others. When individuals are less closely involved and have to deal with each other less intimately, with others looking on, there could be winners and losers. Winners could be individuals who prefer to operate alone and at a distance from others without being closely questioned. Losers could be without familiar advice and encouragement from intimate relatives and personal friends who they rely on for satisfying interactions.

Remedial alternatives for social distancing are talking remotely, phoning, texting, messaging, posting on social media, email letter writing, representation by another or even engaging in identity politics. Compared with face-to-face talking and listening in a chat, they lack emotion, spontaneity, nuances, vernacular and inflections. Their communication may be more reflective, cerebral, figurative and empathetic. Consequences of substituting superficial interaction at nearer distances, with more deliberative distant modes, would be significant for well-being, independence and creativity.

Isolation would have different effects.

Are city councils too small for political competition?

Are bears better at dancing than debating? Presumed Dead is a book that shows what can go wrong in a Westminster System council ruled by partisan duopoly when it supposed to consider approval of development of a megacasino. It takes an independent councillor who is elected mayor to inaugurate a non-partisan council. This is a political crime thriller that exposes weaknesses familiar in town hall politics, with entertaining drama and a positive perspective.

Protect democracy by electing independents

Presumed Dead is a novel about a fictional crime when an Australian city council is considering development of a casino resort. The story reveals how Westminster System politicians are inherently corrupt when their party is not seeking the public good. When a non-partisan mayor is elected, she safeguards the city’s fragile democracy.
