Galileo And Relativity - But More About Inclined Planes And Fun Simulations.

Feb 04 2011 | comment(s)

Talking about relativity one should not forget Galileo's great contributions to - or perhaps in fact foundations of - physics. But more fun are Galileos researches on falling bodies and motion of projectiles, all mainly carried out by either real or Gedanken-experiments, the historians are not quite sure there.

But these Galileo experiments have been realized later and are both on YouTube and in Italian museums. 

Here is a schematic picture, the rolling ball will produce regular bell sounds.

In case you don't know it, the Navy is not the 1970s "Village People" branch of the military.  These guys do some cool stuff and are making even cooler toys to do it with.

Want to find future tech for megawatt-class laser beams in next-generation weapon systems?  The Navy.   Want to go completely science fiction and find work on a railgun with a projectile that rides an electromagnetic current to its target?  The Navy.

A section of the people .... made capital out of their own ignorance.

When I read this I immediately thought of a certain British commentator who denies the anthropogenic contribution to climate change and has attracted a large following.

The Squids 4 Kids outreach program I helped to start up is going strong! We've been doing a number of local dissections, both in and out of classrooms, and shipping squid around the country. They made the news in Florida:
With cameras flashing and video rolling Wednesday, six Canterbury Upper School seniors dissected a 4-foot-long Humboldt squid.

Daphnia Pulex - More Genes Don't Make You Better But They May Help The Environment

Daphnia Pulex - More Genes Don't Make You Better But They May Help The Environment

Feb 03 2011 | comment(s)

Humans have about 23,000 genes and we are at the top of the food chain but the animal with the most genes is the near-microscopic freshwater crustacean Daphnia pulex, or water flea, clocking in around 31,000.

Daphnia is the first crustacean to have its genome sequenced.   The findings are part of a comprehensive report by members of the Daphnia Genomics Consortium, an international network of scientists led by the Center for Genomics and Bioinformatics (CGB) at Indiana University Bloomington and the U.S. Department of Energy's Joint Genome Institute.

Coffee Is Good For You - But Not With 21 Teaspoons Of Sugar

Feb 03 2011 | comment(s)

Coffee can be quite good for you, as any number of studies have shown.   But you still have to take some personal responsibility for moderation because companies like Starbuck's are not going to do it for you.    They're not in the personal responsibility business, they are in the drink business, so when they roll out a new size - the "Trenta" - this spring, all 31 ounces of it, they want you to buy it in any form you want.
Coaches Help Teach Athletes Ethics Also

Coaches Help Teach Athletes Ethics Also

Feb 03 2011 | comment(s)

There are exceptions, of course - some athletes will never be ethical no matter how much coaching they receive and not all coaches are ethical, but overall coaching helps athletes become more than better athletes.   

New survey data from Concordia University says coaches exert moral influence over athletes and how athletes respond.

Biodiesel No More Harmful Than Regular Diesel - Hardly A Great Endorsement

Feb 03 2011 | comment(s)

Biofuels were all the rage in the 1990s, with Vice-President Al Gore declaring them the Holy Grail of fossil fuel replacement.    Unfortunately, no quality science agreed with that assessment yet they have been passed into law anyway by anti-science politicians who saw a way to please part of the voter base.

Found: 54 Potentially Habitable New Planets

Feb 03 2011 | comment(s)

New papers in arXiv show that the Kepler space telescope continues to fulfill its mission of searching for exoplanets, especially those in the 'habitable' zone, a region where liquid water could exist on a planet's surface, around stars.
Ancient Astronauts?

Ancient Astronauts?

Feb 03 2011 | comment(s)

Despite the various claims surrounding the idea of alien visitation in the past, one of the primary arguments has been the creation of immense structures in the past that have been argued as being impossible to create without sophisticated modern technologies.  More to the point, the argument even suggests that it would take quite advanced technologies (even beyond our abilities today), to produce such construction projects.

Invariably the size of the blocks is mentioned (on the order of several tons to several hundred tons), as well as the issue of moving them, positioning them, and of course the precision involved in their placement.

A recent paper in the arxiv describes the observation, in 7 TeV proton-proton collisions produced by the LHC collider in the core of the LHCb detector, of a new decay mode of the particle called "B-sub-s", a meson which is a bound state of a anti-bottom-quark and an s quark.
The Fundamental Nature Of Light

The Fundamental Nature Of Light

Feb 03 2011 | comment(s)

Did you ever wonder why both, Einstein’s relativity theory and quantum physics, in theory as well as experiment, seem obsessed with the nature of light? The velocity of light, light clocks, entangled photons, and so on – why is it always light? This preoccupation is no coincidence. It comes directly from the fact that light does not actually exist. Think I am nuts yet?

Summer Squid Season In The Southern Hemisphere

Summer Squid Season In The Southern Hemisphere

Feb 02 2011 | comment(s)

FIS (Fish Information and Services, the "most comprehensive website for the commercial fishing industry") has a run of recent squid news.

Let's start with Illex argentinus, the Argentinian shortfin squid with a history of contention between fishers from Argentina and the Falkland Islands. After a 2009 crash, Illex rebounded somewhat in 2010 (possibly due to shifting environmental conditions), but so far the catch from the Falklands this year isn't looking good:

We Are All Makers, a TED Talk by Dale Dougherty

The fundamental evolutionary advantage of human beings over all other species on this planet is our ability to make things. We make tools to make more complex tools to make end products that help us survive, thrive, and develop. Pre-humans may have started making simple tools over 2 1/2 millions years ago and serious complex tool-making took off during the Bronze Age just a brief 5,000 years ago.

Victorian Secret: Girls Of Steampunk

Victorian Secret: Girls Of Steampunk

Feb 02 2011 | comment(s)

If you're a Steampunk fan, you are not used to seeing hot girls.   Oh, and you think it's 1995.

Just kidding, there is no better time than going to a local coffee house and seeing a Steampunk club meeting.   It's creative stuff.   But the girls do need work.  So this month at Antarctic Press, Ben Dunn, teaming up with fellow illustrators Fred Perry and David Hutchison, release "Victorian Secret: Girls Of Steampunk" - to maybe teach Steampunk girls how to look.    The site is designed for true Steampunk fans, in that the first page is a useless shockwave Enter button that serves no purpose and after that no modern human could actually figure out how to order anything.
Spartans At Agincourt: Writing Proposals

Spartans At Agincourt: Writing Proposals

Feb 02 2011 | comment(s)

I've been busy with proposal work instead of Calliope.  I have to fund this satellite somehow, and earning money writing corporate proposals is enjoyable work.  Proposal writing is also a strange world. Whether for business, for government, or for grants alike, it's just not quite human.

In face to face conversation, a deal is pretty simple.  "I need you to defeat Henry V." 'We can do it-- we just bested the Persian Army.'  "Deal!"  But not so lucky in proposal world.

A Call to Action

A Call to Action

Feb 01 2011 | comment(s)

It is just before dawn. The raft has rotated on its mooring and aligned to the new direction of the tidal flow. The hydro generator has just come on-line again, and its low whine pervades the silence of the surrounding area. Nothing stirs, no fish nor bird, in this barren landscape. The surrounding waters are dead, rank with the accumulation of salts, minerals and the rotting remains of the life forms, that had been so abundant here. The sun raises, and heralds another day of relentless heat. The air-conditioning struggles in a vain, to achieve equilibrium, and the desalination plant begins the daily task of watering the plants growing in the green house, which pervades much of the area of this small floating kingdom.
On The Origin Of Physical Dynamics And The Reason Of Existence Of Special Relativity

On The Origin Of Physical Dynamics And The Reason Of Existence Of Special Relativity

Feb 01 2011 | comment(s)

The origin of physical dynamics and the reason of existence of special relativity are explored. This endeavour is started by analysing the logic of nature. Next, only mathematics is used in order to explore the dynamics of this model of physical reality.

The model that is described here annihilates the old reality and creates a new reality at each dynamic step. Hilbert space cannot treat dynamics. It contains nothing that supports dynamics.
