Craig Callender: A Graphic History of Time

Craig Callender is a Professor of Philosophy, and Founding Faculty of, and Co-Director of, the Institute for Practical Ethics at UC San Diego in the Department of Philosophy. He is also on the Freedom and Responsibility in Science Committee of the International Science Council, Paris; and Founding Faculty at the Halıcıoğlu Data Science Institute at UC San Diego; Faculty, The John Bell Institute, Hvar, Croatia.

From 1996-2000 I worked in the Department of Philosophy, Logic & Scientific Method at the London School of Economics. I obtained my Ph.D. from Rutgers University in 1997.

His main area of research and teaching is the philosophy of science, with special emphasis on physics, time, and the environment. His book What Makes Time Special? (Oxford University Press, 2017) won the 2018 Lakatos Award. Here are some book reviews: Philosophy of Science, Philosophical Review, Metascience, BJPS, NDPR. He's also won two Chancellor's Associates Excellence Awards, the 2018-19 Award in Research and the 2007-8 Award in Graduate Teaching.

Love the intro, glad you brought it back.

As the block is being perceived there can be no red dot. It's geometric time in which you perceive yourself into existence as part of the block

Imho
Time is iterative and as such relative to the complexity:simplicity by flow dynamics and bifurcations. Feigenbaum constants in time of physics ( light vs “empty space “::time is 0 for light and Infinite for “empty space “) as well as life perceptions, ie., events relative to other events ( as a child everywhere is new, time is slow and as we age fewer new events is perceived as fast passing time) .

What I should say is time is a function of iterations of flow ; perhaps flow of energy:information.

Philosophy allows math and physics to add and multiply sometimes. The number 72 unites both fields in rulial space-time for 72 is a Rule because 72 × 5 bifurcates pi to gain interest via 180°.

Wouldn't every point in the universe today be the exact origin point of the initial light cone of the big bang? (Yes I know that photons of light didn't exist at the moment of the big bang singularity, but humor me with the premise of a fictitious light cone origin point)

The main point is: “there is no time concept without space”
increasing speed reduces space and time that simple equation: distance = speed x time is not simple.
accuracy, stable, speed how humans measure time.
there is a process of generating space not only through the cosmological expansion, creating matter, stars, planets, … but even living organisms are involved in the process including microorganisms …. because they generate dimensions too.
And human brain makes continuous calculations of dimensions thus approximate time measurement.
It is a very complicated process for instance what they said about why plants stop growing is incorrect because it is not only due to gravity.
dimension within dimension,
Of course it is more complicated than that for instance the relation with speed, energy, mass, and so called entropy….. entropy is just a part of more complicated process, the current understanding of space, time, mass, energy, gravity is incorrect even speed.
You can draw a big circle and calculate its diameter calculate how much time it takes then keep reducing the diameter …. “Time has no meaning without space”
(from the mental aspect, there is no time without measurements the way humans understand ) motion, entropy, ... are like frames in larger process but they can not explain space and time alone.
that is why time goes only forward through actions.
(there is no time measurement without memory )
there is misunderstanding about many physical concepts.
steal but don't pollute.

A philosopher's goal is to see how many words can be used to say nothing.

El Tiempo (2.2): abstracción inespecífica de 2do nivel/orden ( pormenorización al respecto ) que representa…
§ un [diferencial (T^(D))]: una contabilización/comparativa – respecto de un sistema no-abstracto dinámico ( pormenorización al respecto ) tomado como referencia: reloj de referencia {asumido un observador/comparador mecánico de ambos sistemas no-abstractos y la existencia de gradientes temporales} – del/entre los ritmo/s de cambio/s de los componentes de /un sistema/s no-abstracto/s.
Ritmo: cadencia (regularidad/periodicidad).
Cambio: transición entre estados de un sistema no-abstracto.
§ una [cronología (T^(C))]: una secuenciación (orden) de sucesos.
Máxima: Si (TBB {existencia no-abstracta}=V/F) ® (Ø$T^(C0)) y Si (TBB {existencia no-abstracta}=V) ® ($T^(D0)=BB).

Que, explicitado aún más quedaría:
§ Relatividad del tiempo: (diferencial) comparativa entre los ritmos de cambios de los componentes de sistemas no-abstractos, donde al menos uno de ellos debe ser dinámico (reloj de referencia) – aunque, un sistema no-abstracto no-dinámico, solo podría ser mensurado como tal, si se desestiman los errores de precisión –.
§ Duración: (diferencial) contabilización de los ritmos de cambios de los componentes de un único sistema no-abstracto dinámico, entre observaciones (reloj de referencia) – mismas que, pueden ser determinadas/detonadas mediante específicos estados no-abstractos de otros sistemas no-abstractos dinámicos o arbitrariamente determinadas/detonadas por el observador/mecanismo –.
§ Paso del tiempo: (cronología) secuenciación de sucesos.
§ …
Nota: ¿por qué razón, el tiempo, no es algo ( pormenorización al respecto ).

PD: el sistema, puede pertenecer a lo físico – aquello explicado por la física –, o incluso, a lo no-físico – aquello presumiblemente tan solo temporalmente inexplicado por la física (que vendría siendo diferente de lo metafísico) –. En síntesis: lo no-abstracto.

Hi in my opinion time is only a way to mesure, events relations. ....

[mcasanovaiii]

m...c... we are trying to have a good day by compassing the universe. there is a nwse to our existence. And the universe is susceptible to climate change...

Thanks Doc... Sorry for being a jerk.. Please accept my apologies..
