He was born in Bulgaria, but moved to Toronto in 1998 where he obtained degrees in Political Science, Philosophy and Economics. About 18 months ago he started the Singularity 1 on 1 podcast and since then has interviewed major big brains, from Kurzweil and Vinge to Wolfram and Stross.

Researchers at the University of Texas Dallas recently demonstrated that transparent carbon nanotube sheets, which can have the density of air and the specific strength of steel, can be used to make objects invisible.
WOAH!!
This news is a couple of weeks old but somehow I must have missed it.
Their website goes on to say:
“This invisibility for light oblique to the nanotube sheets is caused by the mirage effect, in which a thermally generated refractive index gradient bends light array from a hidden object.”
Okay, so it only works on the oblique, so you’re not going to use this to sneak up on anyone anytime soon, but this still blows my mind.
Of course, the research is being funded by “Office of Naval Research, NASA, the Air Force Office of Scientific Research”. Uh huh. Invisible battleships, anyone? I hated playing BATTLESHIP as a kid.
Adam Ford, who invited me to speak at last year’s Singularity Summit in Melbourne, is also organising this year’s H+ Summit in Melbourne, June 25 – 26. He asked me to post some info about it:
The H+ Summit @ Melbourne brings together an eclectic mix of rationalists, futurists, science fiction writers, AI experts, scientists, biotechnology experts, philosophers and theorists to pursue deep philosophical, scientific and technological inquiry, with the aim of being able to discern those changes which are likely to have profound impacts and those which are merely transient and or fashionable.
Technological innovation permeates all aspects of society — from tiny water purification packets and 3d printers, to GPS tracking devices, wearable smart devices, decision support systems, replaceable body parts and personal genome tests. Because technology and society evolve together, it has become increasingly important to develop a greater understanding of how technology is shaping the course of our lives. We are faced with the challenge to continuously become innovative in harnessing and controlling technological development as it accelerates on many diverse fronts. The “pioneers of the future” are faced with the necessity to become ever more resourceful. Even the most conservative thinkers agree that we have already stepped into an era of a profound change. The good news is that our human diversity continues to spawn both inventiveness and novelty.
This conference is brought to you by Humanity+ @ Melbourne (Victoria, Australia). Humanity+ explores how society might use and profit from a variety of creative and innovative thought. Join us for this adventurous journey into the future where you can make a difference! This conference will challenge and enhance your view of the future.
My guest IN THE STUDIO today is John Cook, astrophyscist, web developer, and founder of Skeptical Science, an absolutely brilliant resource for anyone needing to refute the common climate change denialist.
We talk about what motivates climat change denialists (and the difference between being a SKEPTIC and a DENIALIST) and some of the refutations of their most common arguments.
Science nerd that I am, I’m often trying to convince people that time doesn’t exist.
In 1952, in his book Relativity, Einstein writes: Since there exists in this four dimensional structure [space-time] no longer any sections which represent “now” objectively, the concepts of happening and becoming are indeed not completely suspended, but yet complicated. It appears therefore more natural to think of physical reality as a four dimensional existence, instead of, as hitherto, the evolution of a three dimensional existence.
When his lifelong friend Besso died, Einstein wrote a letter to Besso’s family, saying that although Besso had preceded him in death it was of no consequence, “…for us physicists believe the separation between past, present, and future is only an illusion, although a convincing one.”
This idea of no past and no future ties in nicely with non-dualistic philosophy (see The Advaita Show) and actually has major consequences for how we live our lives. If the future has already happened, what’s the point worrying about it? That’s part of the LOTU philosophy I’ve been developing.
If you don’t believe me (or Einstein), try to wrap your mind around this news:
Astronomers have pushed NASA’s Hubble Space Telescope to its limits by finding what is likely to be the most distant object ever seen in the universe. The object’s light traveled 13.2 billion years to reach Hubble, roughly 150 million years longer than the previous record holder. The age of the universe is approximately 13.7 billion years.
The tiny, dim object is a compact galaxy of blue stars that existed 480 million years after the big bang. More than 100 such mini-galaxies would be needed to make up our Milky Way. The new research offers surprising evidence that the rate of star birth in the early universe grew dramatically, increasing by about a factor of 10 from 480 million years to 650 million years after the big bang.
Here’s a great video that zooms into the sky to show you the location of the galaxy:
So here’s the deal: when astronomers look into the Hubble at this object, they are looking back into time. Their “present” co-exists with an event that happened 13 billion years ago. From that galaxy’s perspective, circa 13 billion years ago, we would be in their future. Their “past” is our present. And we won’t be able to see that galaxy’s present (what’s happening on it right now our time) for another 13 billion years, so that means they are in OUR future.
Right?
The same thing happens on a smaller scale when two people are standing in a room together. If one says “let’s both lift our hands when I say ‘now’… “NOW!”” – here’s what happens. When Person A speaks the word “NOW!”, it takes a fraction of a second before Person B actually hears the words or sees their lips move, because that’s how long it takes for the light and sound waves to travel. Person B’s awareness of the Person A’s “now” is actually in that Person A’s past. So Person B’s idea of “now” and Person B’s idea of “now” are actually different. That’s because they both occupy different points in space-time and so their points of reference are slightly different.
