Rand Paul's campaign for U.S. Senate representing Kentucky has launched what is being billed as the "first money blast of the general election."
The campaign seems to prefer the term "money blast" to the grassroots neologism "money bomb" coined by supporters of Congressman (and father to Rand) Ron Paul's bid for U.S. President in 2007-08.
In a campaign that constantly faces down charges of radicalism, the choice of words can make a difference. Ostensibly the campaign wants to avoid violent imagery, including the word "bomb."
Speaking at a recent fundraiser in Washington D.C., Rand Paul said:
'"You'll see that they want to paint me -- the Courier, the Herald, even some of these national newspapers up here -- as being 'extreme,'" Paul said. "One of the answers I learned from my dad, because they tried to do this to him, is flip it around and ask, what's extreme? It's extreme to have a $2 trillion deficit."'
As of 11:00 am Eastern Time, Rand Paul had raised over $33,000 for the day and discouraged supporters at RonPaulForums.com expressed their hope that Rand would raise a lot more by the end of the day:
"I donated first thing (see post # 4) and I'll be back for a second round this evening. If others want to stand by and watch Maddow and Matthews steal a victory from us, they are welcome to do so, but I won't be part of that."
"This student is nearly tapped dry
Eating Mac n Cheese for the next 2 days"
In an e-mail to his supporters today, Dr. Paul wrote:
"My opponent is a big government, tax and spend trial lawyer. He has done little in his life but run for or be in office.
He is exactly what I mean when I say we won't change Washington until we change the kind of people we send.
I am a career physician who has built and run a small business. I believe in fighting for Liberty and for restoring our government to Constitutional limits.
I won't be just another vote in Washington. I will stand up and fight for reform.
I know you support these same ideals. And I am counting on you to stand with me today."

The supreme court today struck down the Chicago gun ban. In a 5-4 decision, the court overturned the 1982 ban on guns in Chicago. The 1982 ban was so restrictive that no firearms could be legally owned or possessed within a domicile in the jurisdiction of Chicago. None.
The statist and fascist mayor Daly had this to say:
Daly said his primary goal would be to protect police officers, paramedics and emergency workers from being shot when responding to an incident at a home. He said he also wants to save taxpayers from the financial cost of lawsuits if police shoot someone in the house because the officer felt threatened.
"If the ban is overturned, we will see a lot of common-sense approaches in the city aimed at protecting first responders," Daley said. "We have to have some type of registry. If a first responder goes to an apartment, they need to know if that individual has a gun."
In other words, we may have to allow people to own firearms, but we will regulate you to death. The safety of police and other first responders is a red herring. In States like Texas, Arizona, Florida and Utah (Along with Vermont and Alaska) have the most liberal laws in regards to gun ownership, and I mean truly liberal. Police there generally do not have a problem with individuals legally possessing firearms. This is a fall back measure by Daly to restrict people based on his illogical and statist world view.
Writing for the court in a case involving restrictive laws in Chicago and one of its suburbs, Justice Samuel Alito said that the Second Amendment right "applies equally to the federal government and the states."
This is a happy day for liberty loving people, even with the continued threat from social progressive statists like Daly, Obama and others. Alito's affirming that gun ownership extends to the states sends a clear message to left wing progressive ideologues that our natural rights will be defended, promulgated and affirmed at all levels of government, no matter how much it pains them in their pursuit of making us Farm Animals®.

Players complaining about the new ball: It’s one of the traditions that returned like clockwork with this World Cup, along with egregious diving, English misery, and American fans perking up when the team performs and then swearing off soccer for another four years when USA crashes out.
But while equipment discontent typically fades as the tournament enters its final stages, anger toward World Cup 2010’s Jabulani ball won’t subside. So Caltech scientists decided to find out for themselves: They took the ball into their lab’s wind tunnel to see if it’s really so bad.
If you’ve spent any time kicking around a soccer ball, you’ll remember that it isn’t a perfect sphere, but rather is made of geometric panels with grooves in between. But while a traditional ball contains 32 panels, the Jabulani contains only 8, which made the team led by Beverly McKeon suspect there could be something to the complaints about its erratic behavior.
Consider the history of the golf ball, which was smooth back in the mid-1800s. “The Scots learned the hard way,” McKeon said. The addition of dimples made for a rougher surface but a narrower wake and less drag, which contributed to straighter, longer trajectories. To some degree, the Jabulani represents a shift in the opposite direction, even with tiny ridges covering its skin. Caltech’s study suggests that it starts with a smooth — or laminar — airflow, shifts to something more turbulent, then shifts back again [Los Angeles Times].
The scientists say those shifts they saw in the lab (see video here) could be responsible for the odd reactions we’ve seen from goalkeepers in this World Cup, like English ‘keeper Robert Green’s notorious misplay against the United States.
“So as the goalkeeper sees the ball coming, it suddenly seems to change its trajectory,” McKeon said. “It’s like putting the brakes on, but putting them on unevenly” [Los Angeles Times].
Altitude also could be adding to the Jabulani’s misbehavior. That’s the defense coming from Erik Van Leeuwen of Adidas, the ball’s manufacturer.
Six of the 10 World Cup stadiums are above 1,200 meters (3,937 feet), where the air is thinner. That may be affecting the Jabulani’s movement, Van Leeuwen said. A ball kicked at altitude travels 5 percent faster than one kicked in Durban, which is at sea level, he said [Bloomberg].
FIFA, soccer’s governing body, says it’s aware of the concerns about Jabulani. But for at least the rest of this tournament, players are going to have to get used to it—or blame the ball if they lose.

Here’s the situation: You spot Roman attack ships headed for your shores. Do you order your troops to ready the cannons? Or–in an ancient MacGyver move–do you use a parabolic mirror, focusing the sun’s rays to set the ships on fire? Though the latter is clearly more suave, recent research has shown that the 212 B.C. legend about Archimedes’ mirror defense is unlikely: He probably pulled out the big guns instead.
Cesar Rossi, a mechanical engineer at the University of Naples in Italy, figured out the numbers. A steam cannon–like the ones Leonardo da Vinci drew in the 1400s–could use less than a tenth of a cup of water to fire a hollow clay ball, at 134 miles per hour, to hit a target 492 feet away. For comparison, an 1854 American Civil War Howitzer cannon could fire a ball about ten times farther–a little less than a mile.
Rossi presented this research at the International World Conference in Syracuse, Italy (the site of the historic Roman attack on the Greek colony) earlier this month. He told LiveScience that after looking at both the historical references to the battle and the feasibility of using the mirrors on moving ships, that the cannons were “much more reasonable than the use of burning mirrors.” The hollow clay cannon balls could have been filled with a mix of incendiary chemicals that would have set the ships afire on impact, Rossi suggests.
In 2005, MIT students recreated the mirror defense and managed to set a wooden “ship” ablaze. On the roof of a Cambridge parking garage, they scorched the ship, but their test required ideal weather conditions and a stationary target. Rossi hopes to team up with other researchers to create his own reenactment using the steam cannons.
Cannons or mirrors, Archimedes couldn’t save Syracuse–and the Romans’ success meant Archimedes’ end.

Water is marvelously expressive stuff . . .
This week marked the continued transition from Shuttle operations to future opportunities. This was highlighted by ground breaking on the new Exploration Park at the Kennedy Space Center. Like research parks at other NASA centers, KSC's Exploration Park is an initiative to attract businesses to KSC. This week also marked the anniversary of one very important past mission.
Shuttle Shakeup Continues
The final two missions of the shuttle program will both be pushed back due to a variety of different technical and logistics issues. The launch of STS-133 will slip about a month and a half from September 15 until October 29. STS-134 was supposed to launch this November will now launch no earlier than February of 2011.
The payload on one of the flights has had mechanical issues and cannot be delivered in time for launch and there are two communications blackout periods that fall within the period in which these launches would occur. Add to that the fact that both the European space Agency's ATV and the Japanese Space Agency's HTV are scheduled to fly missions in this period.
Given all these different factors it has been decided that it would be best if the launch dates would be pushed back so as to account for all the variables. There still has not been a final determination as to whether there will be an additional flight added to the shuttle's manifest. That determination is due by the end of this month.
NASA and Space Florida Break Ground on New Research Park
Florida Governor Charlie Crist announced the official groundbreaking of Exploration Park, KSC's next-generation technology and commerce park on June 25. To mark the groundbreaking Lieutenant. Governor Jeff Kottkamp, local officials and senior leadership from Space Florida and Kennedy Space Center (KSC) gathered on the grounds of NASA's Space Life Sciences Laboratory (SLSL) where ISS-bound payloads are prepped for flight.
The SLSL will be the first building of Exploration Park. Exploration Park will host a wide range of aerospace-related activities for commercial, civil and military tenants. The park will be close to existing launch and payload processing facilities, providing easy access to space launch facilities.
Phase 1 of Exploration Park is currently expected to include eight new buildings with some 315,000 square feet. Space Florida has signed a 60-year lease with NASA to develop 60 acres of usable space on KSC property for the park, which will also incorporate the adjacent SLSL and enable other new laboratory and high bay capabilities. To date, six Letters of Intent have been signed by potential tenants of Phase 1 facilities.

This Week in Cape History
June 27, 1995: NASA launched space shuttle Atlantis on mission (STS-71) on its way to dock with the Russian Mir Space Station. This mission was the first cooperative effort between the United States and Russia since the Apollo-Soyuz Test Project during the summer of 1975. The five-day docking between Mir and Atlantis marked the formation of the largest spacecraft ever put into orbit up until that point in history. It also marked the 100th manned space launch by the U.S.

I extremely nerded out and pleased and squeeified to announce that I’ll be at w00tstock! At Comic Con. On stage.
I know.
w00tstock, for those helplessly normal of you out there, is the premier nerd event in the Orion arm of the Milky Way. Hosted by singers Paul and Storm, Mythbuster and My Close Personal Friend Adam Savage™, and my long-standing and partially-requited nerdcrush Wil Wheaton, w00tstock is billed as "Three hours of geeks and music", which is apt enough. Everyone I know who has gone has raved about it.
And cripes, the talent they get. Bill Corbett, Mike Nelson, and Kevin Murphy from Rifftrax, née Mystery Science Theater 3000. Chris Hardwick, aka The Nerdist. Len Peralta, about whom you’ll be hearing more on this blog pretty shortly. And oh my FSM, I’m really thrilled that my favorite fire-haired songstress Marian Call will be there as well. Apparently I wasn’t the only one who sent a note to TPTB to get her on stage.
One cool thing about w00tstock is that all the stuff done on stage is Creative Commons licensed, so it goes up immediately on Flickr and YouTube. In fact, there are a lot of videos from previous versions online you can check out. If you’re a bona fide nerd you’ll enjoy them.
To say I’m excited and honored is like saying a gamma-ray burst is kinda bright, or a neutron star is somewhat dense, or a Planck length is a tad minuscule.
I’m that excited.
And of course initially panicked over a topic. But then Mrs. BA inspired me, and suddenly, full blown like Minerva from the brow of Jupiter, an idea burst forth from my brain. So now all I have to do is put it together and keep it to ten minutes. Good thing I’m not long-winded.
Anyway, you can get tickets for this, but you’d better hurry because Comic Con is Geek Central and I’m sure they’ll sell out this week.
And as if that’s not enough, I’ll have even more Comic Con news soon. Mwuhahahaha!
