Einstein and relativity
The early modern physicist Isaac Newton had presumed an unperceived yet real flow of time. To Newton, time is a dynamic physical phenomenon that exists in the background, a regular, ticking universe-clock in terms of which one can objectively describe all motions and accelerations.
8/
Then, Albert Einstein came along.
In 1905 and 1915, Einstein proposed his special and general theories of relativity, respectively. These theories validated all those long-running suspicions about the very concept of time and change.
Relativity rejects Newton’s notion about time as a universal physical phenomenon.
By Einstein’s era, researchers had shown that the speed of light is a constant, regardless of the velocity of the source.

Parmenides wasn’t the only skeptic about time. Similar reasoning regarding contradictions inherent in the way we talk about time appears in Aristotle, in the ancient Hindu school known as the Advaita Vedanta and in the work of Augustine of Hippo, also known as St. Augustine, just to name a few.

He reasoned that, if the future is real, then it is real now; and, if what is real now is only what is present, the future is not real. So, if the future is not real, then the occurrence of any present event is a case of something inexplicably coming from nothing.

Ancient philosophers on time
Ancient philosophers were very suspicious about the whole idea of time and change. Parmenides of Elea was a Greek philosopher of the sixth to fifth centuries BCE. Parmenides wondered, if the future is not yet and the past is not anymore, how could events pass from future to present to past?

Human beings have been thinking about time for as long as we have records of humans thinking about anything at all. The concept of time inescapably permeates every single thought you have about yourself and the world around you. That’s why, as a philosopher, philosophical and scientific developments in our understanding of time have always seemed especially important to me.

But go ahead and try to actually verbalize just what is meant by the flow or passage of time. A flow of what? Rivers flow because water is in motion. What does it mean to say that time flows?
Events are more like happenings than things, yet we talk as though they have ever-changing locations in the future, present or past. But if some events are future, and moving toward you, and some past, moving away, then where are they? The future and past don’t seem to have any physical location.

What is time? Rather than something that ‘flows,’ a philosopher suggests time is a psychological projection
by Adrian Bardon, Professor of Philosophy at Wake Forest University
“Time flies,” “time waits for no one,” “as time goes on”: The way we speak about time tends to strongly imply that the passage of time is some sort of real process that happens out there in the world. We inhabit the present moment and move through time, even as events come and go, fading into the past.

The passage of time is inextricably bound up with how humans represent our own experiences. Our picture of the world is inseparable from the conditions under which we, as perceivers and thinkers, experience and understand the world. Any description of reality we come up with will unavoidably be infused with our perspective. The error lies in confusing our perspective on reality with reality itself.
A Brief History of the Philosophy of Time by Adrian Bardon, 2013
Adrian Bardon's A Brief History of the Philosophy of Time is a short yet thorough introduction to the history, philosophy, and science of the study of time-from the pre-Socratic philosophers through Einstein and beyond.

A Brief History of Time by Stephen Hawking, 2011
A landmark volume in science writing by one of the great minds of our time, Stephen Hawking's book explores such profound questions as: How did the universe begin--and what made its start possible? Does time always flow forward? Is the universe unending--or are there boundaries? Are there other dimensions in space? What will happen when it all ends?

About Time by Adam Frank, 2011
The acclaimed, exhilarating journey into the science of time, from Stonehenge to the Big Bang and beyond.
![“A fascinating and comprehensive survey of how technology – from farming to railways to telegraphy to the internet – has changed our everyday concept of time. [Frank] is excellent at showing how our ideas of human and cosmic time have evolved hand in hand ... Compelling.”
Marcus Chown, New Scientist
“Eloquent ... [Frank’s] trek through the history of humanity takes a parallel look at how we have gained a deeper grasp of the Universe during our time on Earth.”
Nature
“A phenomenal blend of science and cultural history ... Ultimately, Frank argues that recognizing our place in the ongoing narrative of the creation of cultural time and cosmic time – moving beyond the cosmology of the Big Bang (of which ‘ours’ may be one of many) – is what will allow mankind to enter a new, global era of time and culture.”
Kirkus Reviews, starred review
“This will fascinate anyone curious about the nexus of astronomy and history and, of course, time.”
Library Journal
“Frank ponders fresh ideas in cosmology ... and how the human perception of time will change in the future.”
Washington Post
“This one is a must-read! The book does a wonderful job weaving together the story of human history and time in the context of the universe. From the Big Bang to the Renaissance to cell phones to the multiverse, [Frank] takes extremely complex ideas and makes them easily digestible, endlessly fascinating, and fun. About Time will make you think.”

About Time by Adam Frank, 2011
The acclaimed, exhilarating journey into the science of time, from Stonehenge to the Big Bang and beyond.
“‘Time’ is the most used noun in the English language, yet we still don’t really understand it. Adam Frank tells the fascinating story of how humans have struggled to make sense of time, especially in the context of the universe around us. From prehistory to the Enlightenment, through Einstein and on to the multiverse, this is a rich and inspiring tour through some of the biggest ideas that have ever been thought.”

A Very Brief History of Eternity by Carlos Eire, 2010
What is eternity? Is it anything other than a purely abstract concept, totally unrelated to our lives? A mere hope? A frightfully uncertain horizon? Or is it a certainty, shared by priest and scientist alike, and an essential element in all human relations?

"El mar y yo"
Fue un día que bañada en los marullos,
De un mar mágico y sereno
Que escuché los murmullos de sus olas
Que insistían golpeándome sin freno
«Mucho tiempo llevamos esperándote
Corre ya sin demora a nuestra casa»
Y la voz que escuché se repetía
Cada ola que golpeaba, hipnotizaba
"Ven conmigo novia mía, es el día...
Ven conmigo novia mía, a nuestra casa.
Navegué el amplio mar que llevaba hasta

Have you ever seen the granulate shellback crab (Hypoconcha arcuata)? Growing about 0.6 in (1.4 cm) long, this unusual-looking crustacean inhabits coastlines along parts of the western Atlantic, with a range that includes parts of the United States, Mexico, and Brazil. Unlike hermit crabs—which hide inside their chosen shells—this critter uses its posterior legs to secure shells onto its back, often shouldering pieces larger than its own body, as a defense against foes.
🦩Did you know? A flock of flamingos is called a flamboyance—and it’s easy to see why! With their bright pink feathers, long legs, and graceful necks, these colorful birds command attention wherever they go.
There are six species of flamingo worldwide. They are highly social creatures and often gather in large numbers. The largest flamingo colony in the world can be found in Tanzania, where more than 2 million birds have been observed at one time.
