Yet history shows that the greatest "techies" (Kepler, Newton, Galileo, and others) did not work alone and were certainly depending on others to establish their theories and measurements - and many were very much "humanists" and universal thinkers who cared very little about politics and frontiers. Even Einstein who was a key player in developing nuclear power was against any use of it in military conflict. So, I wou…

I believe Newton and Galileo worked alone for much of their lives. Kepler was far more intellectually generous.

Newton was certainly known to be a recluse, but he was a teacher in university and spread knowledge around him. Besides, all his work rested on centuries of work before him and he recognized the heritage of others in his discoveries.

Yep, all very true and totally agree. Never just one individual responsible, I just dropped the name of the biggest one for the sake of briefness. I think it was Danton that said something like, "My only regret is to go before that rat Robespierre" when he was giving his last words after being arrested for realizing how screwed up the revolution had become with his and other's control of The Committee of Public Safet…

> Jean-Paul Marat was made out to be a martyr on his death instead of despised for his role in fueling the flames. Very true. He was well known to be claiming "100 000 tetes doivent tomber" (100 000 heads must fall) in order to get rid of the so-called "internal enemies". Interestingly, while he had a "martyr" image, so did Charlotte Corday (who killed him) at least in the eye of numerous writers post-Revolution. If…

I'd love to see it actually. Tried to contact you via your website form, but it wasn't working. I'll just send a tweet instead.

That article says they use dolphins for meat and income. It seems a little easy to sit in an armchair next to a fridge full of supermarket-bought food and complain about what islanders do to eat. Presumably, the money they claim they weren't paid would've been used on other sources of food, and when unpaid, went back to what they were doing before, with a little extra effort to piss off the non payers.

While i'm not sure i agree with you or the grand-parent post†, i think your argument doesn't help refuting the grand-parent's main point. ComputerGuru's main point was showing how similar dolphins are to humans, in the way they live and socialize, and stating that, because of those reasons, killing them is wrong. Yes, they might be doing it for their own living, but that doesn't make it any less wrong. In the end, we…

Well, you need a human to make a difference.

Does parasite gives a shit what meat he is eating, dolphin or human. Does human gives shit what meat he is eating, usually not until you give him pretty pictures and moral books and tell what to do.

Children love meat, children can watch how pig is squeaking and is slaughtered, split open and chopped up, it is more of wow event that anything else. Same pig yesterday he rode and and considered a friend, had a name for it.(this is nothing to do with children who live in boxes, this is children in farm environment, hunter environment).

Still, human is interesting, because sharks do not hunt human for food, if they bite one it is more or less curiosity. Same with many other predator species, it is like human is somehow ignored.

Yet, only we can make sense out of it. By giving it the meaning.

But everything is opinion of mine and yours as there is no built in meaning and sense into anything.

We stick to opinions we feel fancy until we don't and repeat until we die.

There should be my email somewhere in the profile, no? (check again, just added in profile)

This is a form of "tonic immobility" in sharks (chickens have the same reaction if held whilst looking at a line drawn away from them) It's an attempt to feign death / stand immobile whilst danger passes. Its effective in sharks as they need water passing over their gills so if they stop swimming they are dependant on current. Of course orcas are big enough to turn a shark over - your average guy in a chain mail suit…

http://en.wikipedia.org/wiki/Apparent_death "With tiger sharks 3–4 metres (10 to 15 feet) in length, tonic immobility may be achieved by placing hands lightly on the sides of the animal's snout approximate to the general area surrounding its eyes." Nah, that sounds easy.. ^^

I have a plan - we post the above link on Reddit then we put a hundred bucks on what the next Darwin Award winner dies of

Dolphins are exactly why I feel SETI is such a misguided (in a sweet way) effort. Here we are, searching for extraterrestrial intelligence while we can't even communicate with the other intelligent species on our own planet. Glad to see we're making progress though!

SETI are one of the biggest supporters of research into dolphin vocalisations. Laurance Doyle, who is at SETI, is one of the pioneers of the field.

Wow, that second link was a really good article. Thanks for sharing. I didn't realize crows were that camera shy or observant that people were watching them back. Makes sense though they they would be paranoid when someone or some thing is paying them too much attention as 99% of the time it means something bad will come next.

Once I cornered a rabbit in my ally. The usual way out was blocked, and the rabbit was frantically searching the far wall for another escape while I watched. After a bit I was momentarily distracted, and the rabbit choose that moment to dash past me. Apparently the rabbit knew my attention had turned. As would a crow. They don't need our special mental abilities -- language and lambdas -- to model the mental states o…

Same way cats can detect whether you focus your attention at them or not.

Eyes are very popular organ and seeing eyes and recognizing what they are looking at is very useful skill. I think animals get this skill as soon as they have enough physical computing power to achieve this task.

That sounds very intriguing. However, it's likely that any extraterrestrial intelligence capable of maintaining life on it's home planet, will have an understanding of their fellow life forms, which is more than we have.

What makes you say that? It doesn't take too much knowledge to maintain a biosphere, otherwise it would have collapsed long before humans arrived on Earth. It seems more to do with how cautious you want to be, how far a race is willing to push the environment in return for faster progress. I also suspect that any extraterrestrial intelligence capable of making a signal detectable by our equipment would have given up…

Well. It did. Multiple times.http://en.wikipedia.org/wiki/Extinction_event

It's just that things tend do kick back in if you give them few millions of years.
