Are There Any Real Inventors Left?

si3n4 Todays inventions are not todays products (417 comments)

Author is confused because he focuses only the ideas in commercial production. How long were lasers or LEDs or transistors or any number of fundamental inventions in existence before they made large commercial entrances that popular culture recognized? He needs to go into the labs and see how many fundamentally new items have been created in the last 10 years that are now in the world of development (and yes invention ) that reduces them to practice and economic accessibility and then tell us the cupboard is bare. Some guy whining about the shallowness of popular acclaim with a shallow assessment of the world.

Does US Owe the World an Education At Its Expense?

si3n4 it might be another option but not the smart one (689 comments)

the smart one is to use the fact so many people want to come here to draw on the brain pool of the world and keep the country in a strong technical position that keeps us rich and keeps it such a nice place to be - see how that feedback loop works ? We should make it possible for the talented to stay.

Brain Scan Can Detect Autism In Infants

si3n4 this is "insightful" Re:Not early enough. (166 comments)

Downs is not autistic . I am not completely opposed to this point of view but an insightful person would recognize the slippery slope here. In some cultures being female is a 'defect' and children are aborted. I think we shouldn't walk that easily into arbitrary determinations of worth ...

Gut Bacteria Exert Mind Control

si3n4 Re:Was this unexpected? (221 comments)

not unexpected but unexplored I think. The impact of our digestive zoo seems more revealed each day - impacts on creating and suppressing disease , impact on the amount of nutrients we can get from the foods we eat , now perhaps contributions to our mental functioning. Maybe this got over hyped a little but I think the work is still interesting.

Cisco Accused of Orchestrating Engineer's Arrest

si3n4 Re:I don't understand how this is 'orchestrating' (160 comments)

Mod this guy up - whatever the truth of the case it seems like 10 months should be enough time to provide the evidence. Always hate to see the Canadians fall short - who's going to be our positive role model..

The Dying DVR Box and Woz Wisdom

si3n4 so I RTFA and it's interesting but incomplete (207 comments)

this is a lovely idea but surely isn't a complete vision of an education - part of the reason there are standard classes with standard exercises is that there are skills you need to have and background knowledge you need acquire to do the kind of cool stuff he envisions. You can't stand on the shoulders of giants if you don't climb up there and that is a lot of stuff to learn. Which doesn't mean that adding projects like this that drive a student to creatively exercise knowledge along the way wouldn't enrich and build on that understanding - just that you sort of do have to know what is already known to get to the point you can can add something new.

The Logical Leap: Induction In Physics

si3n4 Re:Am I missing something? (630 comments)

Please mod this guy up. The best statement in this string about the fundamental error in the topic as presented . Anyone who feels they have come to understand the TRUTH about the world is welcome to it but that's not what science is about at it's core. It's about the creation of an outcome I desire by understanding "how" to create it. It's about finding the mathematical relationships between aspects of the reality we perceive - directly or through our tools. How we come to identify which mathematics might apply , envisioning models that build from our " "first-level" generalizations which are directly, perceptually obvious" , is an interesting topic but it never relates to discovering truth in the sense philosopher's seek.

Hypersonic Radio Black-Out Problem Solved

si3n4 Re:The shuttle doesn't (currently) black out (88 comments)

thanks for the comment - I realize this quickly devolved into a discussion about what was or wasn't said in the article but it is interesting that the shape of the vehicle can create a hole in this plasma and thus provide another solution to the issue . Maybe it's not always possible to design the object involved to create this hole and the plasma antenna is a useful alternative, but in any case it was interesting to me to know this other 'solution' exists....

SAP Ordered To Pay $1.3 Billion To Oracle

si3n4 Re:Jingoism? (151 comments)

Thank God no European nation ever had a court system rigged against a minority - then every decision they made today would be suspect too. Go ahead and complain if you have the facts that bear on the case but spare us the historical references...

GNU/Linux and Enlightenment Running On a Fridge

si3n4 where's the old standby comment (222 comments)

okay , I carefully read all the posts and am deeply disappointed - not one comment about needing network connections so someone can get a bunch of these and build a Beowulf cluster. Missing the old Slashdot standby comment. Clearly the next step is to put biological sensors in the fridge to tell you when the spore count is spiking and identify the most probable substrate.

New Scientist story - isotope bochemistry

si3n4 si3n4 writes  |  more than 5 years ago

si3n4 (540106) writes "Bonds for the heavier isotopes of a chemical are often stronger than for the more abundant form . New Scientist has a story on belief that isotopic substitutions in biologic compounds might toughen them against free radicals (or later in story radiation) providing life extension . http://www.newscientist.com/article/mg20026841.800-would-eating-heavy-atoms-lengthen-our-lives.html"
