“Here we are, trapped in the amber of the moment”*…
We’ve all heard it before: There’s no time like the present. Broadly speaking, of course, it means to “seize the opportunity right now,” or maybe in my case, to avoid procrastinating. From a psychological perspective, this makes a lot of sense. As humans we experience time “passing,” and there is a special quality to the present moment. Hypnosis and dreams aside, there is no way to directly experience either the past or the future in the same way we experience the present. But is the aphorism true? Does modern physics actually tell us that there’s no time like the present?
Our best current physical theory of space and time is general relativity. Prior to Einstein’s revolution over a century ago, physics considered time to be an “external parameter”—an independent, fundamental feature of reality not influenced by any other factor in the universe. Whether or not the passage of time is real or illusory (this is an age-old philosophical debate that predates Einstein and is indeed not settled by his theory), we now know that time intervals are not external or universally determined. Time is an internal component of a physical system, a dimension intertwined with three spatial dimensions. Taken together, this is “spacetime,” and is influenced by varying factors and is influenced by varying factors, including speed (relative to other observers or systems) and gravitational forces. Because the theory of relativity posits the constancy of the speed of light for all observers (even if they are moving relative to each other), spacetime itself must dilate and the concept of a time interval becomes elastic.
As a result, there is no universal notion of the present that applies equally to all observers. What looks present to me could just as easily be in someone else’s future, and in a third person’s past. Simultaneity is relative…
Think there’s no time like the present? As Mark Shumelda suggests, modern physics begs to differ: “Actually, There Is a Time Like the Present.”

As we cogitate on carpe diem, we might send playful birthday greetings to Johan Huizinga; he was born on this date in 1872. A Dutch historian and one of the founders of modern cultural history, he is probably best remembered for his 1938 book Homo Ludens, in which he argues for the importance of the play element of culture and society, suggesting that play is primary to and a necessary (though not sufficient) condition of the generation of culture.
“A subtractive 3D printer”…
If you are a fan of the Sci-Fi genre of the robot apocalypses you may well not want to give a robot a chainsaw to wield. If, on the other hand, you are a creative artist then it seems well worth the risk…
In this case the robot is a standard industrial arm with an electric chainsaw mounted where the gripper would normally go. There is no doubt that a gas driven chainsaw would be far more threatening but even so, when the software starts it up you really hope that humans are well out of reach…

As we brush up on Asimov’s Three Laws, we might spare a thought for Johan Huizinga. A Dutch historian considered one of the fathers of cultural history, Huizinga was the leading theoretician of play (e.g., Homo Ludens. Versuch einer Bestimmung des Spielelements der Kultur (1939), translated as Homo Ludens, a study of the play element in culture). He was interned by the Nazi occupiers of Holland, of whose policies and practices he had spoken and written critically since the 30s. Huizinga died in detention on this date in 1945.
