joseph purrazzella So the whitening of the pigment at each laser pulse is only temporary? If there weren't white blood cells to remove the pigment the color would come back?
October 30, 2014 18:22:39 · Reply
Ryan Lidster I think (but I'm by no means sure) that the whitening is actually just the epidermis responding to the laser, and that the pigment underneath is still present but made less visible temporarily. Perhaps Dustin or Dr. Labbert can help clarify that.

Alex Southwell (Me = Not Doctor) I would think that both would be happening, the epidermis would be swollen and discolored in a way that would make it more opaque, but also the breaking up of the ink particles would make them less pronounced or look faded.

Kristy Well, I ended up having to go back to see power soccer team updates. They won't use email! But a word of caution to all: I had the experience of seeing the scope of my photos that FB has uploaded when I made my "Year in Review" video. I wanted a specific pic, and did not see it. At the time, there was a "Customize" button at the bottom of the template, so I hit it. And then I went to "Access All Photos".. and my jaw hit the floor. FB had photos of my missions in Iraq -- ALL of them, not the select few I had chosen to put in an album. They had gory photos of blown-off limbs, genitalia, guts -- and showing the faces of everyone. Military mission photos, not redacted, that I took in 2004 on a long-gone digital camera, uploaded to a long-dead iMac. When I made that album (in 2007, in Italy), FB had grabbed every photo on my computer. I know this because I have since lost the CD of photos, and the computer was gone. I took a couple of screenshots for proof, but it was very disturbing. The wording of FB's "privacy" (ha!) statement allows FB to access all photos on your device (computer or camera) when you upload. Be careful. Put everything you value and want to protect on your portable hard drive, disconnect, THEN upload what you want. Because otherwise, you've given them the keys to your house.

ChristianBitterlich Hi Destin, did you know that the Bauer Media Group is one of the initiators and enforcing promotors of the German law called "Leistungsschutzrecht" (ancillary copright), which they created against googles news snipets, but enforcing them also on blogger. However facebook is not there only harvesting ground ( http://www.schoen-und-fein.de/dreister-bilderklau/ ), recycling content without correct linking, asking or even paying is common sence of the Bauer Media Group. Talking to them seems to be a waste of time while they can collect more money on the side adds (10428 EUR for 1/3 A4-page paper add with a volume of 150k) or your example with linked visitors for facebook. The only efficient way is to claim an interim injunction combined with a restrictive covenant/cease and desist agreement. Claiming a portion of the "add-money" or value of the used content is at least in Germany a very long way (up to 3 years) before the court sets a positive verdict for the content robbet prosecutor. It's a bit funny that the motion picture industry is enforcing closing of websites, which are just linking content and facebook, which has listed in there terms and conditions "that you are not allowed to upload content, where you are not the legal owner" still allows the firm to post new or the same content again. At least youtube has a counter, where the poster will be banned after a certain amount of content fraud.

Jeff Dzado Wait...I thought the closer you are to the planet, the faster you had to move to keep missing it. You're saying the velocity of the Soyuz is SLOWER than the velocity of the ISS? I fully understand that the Soyuz is orbiting Earth more quickly and 'catching up' to the ISS.
March 24, 2015 17:45:46 · Reply
Paul Spooner Awesome video! Just one problem though. At 7:34, the visual annotations mention that Soyuz is moving slower, but orbiting faster. But in actuality, the Soyuz is both moving and orbiting faster, and the ISS is both moving and orbiting slower. Then at 9:02 you make the same mistake, only in the voice-over.
March 24, 2015 17:50:49 · Reply
Trevor Madge I think he said it correctly... Soyuz is moving slower at about 17,000 miles per hour and the ISS is moving at about 17,500 m/h. But, because Soyuz is closer to the earth, the distance it needs to travel to go around once is smaller than that of the ISS, so it gets around it faster.... Soyuz is moving slower but orbiting faster.
March 24, 2015 19:54:34 · Reply
Paul Spooner Your numbers must be off. If both orbits are circular around the same body, then the smaller one will have the higher velocity.
March 24, 2015 19:57:06 · Reply
Trevor Madge If both are orbiting at the same speed (1 "lap" every 90 minutes) than the one with the larger orbit would be travelling faster because it needs to go farther. Just because they're orbiting the same body doesn't necessarily mean one is faster than the other. In this case, they said that Soyuz is travelling around 17,000 m/h and orbits in 86 minutes, and the IIS is travelling around 17,500 m/h and orbits in 90 minutes.

Paul Spooner You have understand geometry correctly, but misunderstand orbital mechanics. Bodies simply can not orbit at whatever velocity they like.
March 24, 2015 20:08:35 · Reply
Trevor Madge You're probably right that my understanding of orbital mechanics is a little off. I decided to do a little reading and I've been looking at the equations here: http://en.wikipedia.org/wiki/Circular_orbit If I understand them correctly, as the radius increases, velocity decreases and orbital period increases. That seems to explain why the ISS is taking longer to travel around the earth, but it doesn't explain why it's travelling faster. Maybe it has to do with the difference in mass between the Soyuz and the ISS? That's the only other variable in those equations. A larger mass would require a higher velocity.

Evan Hagerty I would disagree with you Paul;what the Astronaut said made sense, although it was a bit confusingly put. One way to look at it through the simplified equation (V^2)/r=9.81m/s^2, which shows that as the radius of orbit increases, the linear velocity of the orbiter increases. Another perspective is that in order to increase the radius of circular orbit the ship must fire a rocket (twice) with the force of this acting in the same direction as the velocity of the ship. The first burn increases kinetic energy, then this is "traded" for gravitational potential energy as the rocket orbits to it's slowest, farthest out point, and then the kinetic energy is increased once again until the orbit is circular. The confusing part is that while increasing the radius of orbit leads to a higher linear velocity, it leads to a longer orbital period. Sorry if I've misunderstood your perspective on this. I found the video fascinating, and I can tell you did too, so cheers!

Nick Vahalik Really, really cool. This is a GREAT way of visualizing something that radio operators have to consider every day: VSWR (Voltage Standing Wave Ratio). With VSWR you're dealing with RF frequencies that are reflected back at a transmitter due to an impedance mismatch on an antenna at the end of a feed line. So instead of the power that should be going to your antenna that power (or some portion of it) comes right back at you, creating standing waves on the feed line like you see here in the video. Since AC power (really any frequency) can be shown as a vector, you can "do math" on them. In this scenario, you've got nulls in between two opposing vectors that are *in phase* and the peaks and valleys are added together and grow accordingly. In the radio world, you're dealing with kilo-volts being sent down a coax feed line and if you send down a kilovolt and let's say, 70% of that power is reflected back to you in-phase, those spikes can exceed the voltage rating of a cable. So instead of a drop of water exploding as in your video, this voltage spike can burn through your coax, cause fires, damage equipment, and otherwise ruin your day.

Weatherlawyer I have a difficult one for you I can't prove this is not just coincidence but when a weather system steps off the Eastern coast of North America A significant earthquake occurs in the Aleutians. This has a reciprocal that before a weather system arises a seiche is initiated in the ocean in which the next tropical storm will occur. The epicentre will be in the region where the storm peaks and lie on the storm track. As proof of this two or three related earthquakes always occur with the demise and a blocking Low will contain two or three parallel fronts. I only know for sure they occur with the North Atlantic but am pretty sure they do the same with the North Pacific. Could you twist the arm of some seismologist to see if they can follow this idea with whatever is required.

A. Ron Carmichael This is MOSTLY correct. The failure to consider the lateral sliding of the bowstring OFF OF THE FINGERS, which determines which way the arrow is going to flex, and which way the back end of the arrow is going to MOVE, actually altering the initial trajectory (direction of travel) of the point of the arrow, is EVERYTHING about determining whether archer's paradox exists or not. With the compound bow demonstrated, the archer uses a mechanical release that completely ELIMINATES the lateral slide, thus at no point in the arrow release is the arrow aimed OFF of the target as it is when an archer is holding the string with fingers. The paradox is not that the arrow does not "hit" the riser, the paradox is that the arrow IS NEVER POINTED AT THE TARGET BY THE ARCHER WHEN AIMING through a sight. As far as "being smart enough to know which way the nodes are flexing so you can hit the aspirin, just move the archer back 4 feet, changing the distance so he (one of the world's most distinguished and excellent demonstration archers) has to completely readjust his aim. He can do it but it will take him some shots to home back in. THAT IS THE PARADOX: NOT THAT THE ARROW DOESN'T HIT THE RISER/BOW, BUT THAT THE ARROW SHOT IS STARTED OUT AIMED COMPLETELY TO THE SIDE OF THE TARGET, YET STRING SIDESLIP (from the fingertips) CAUSES IT TO BE POINTED DURING A FEW MILLISECONDS DIRECTLY AT THE TARGET. THAT is the paradox. That the shaft flexes in nodal behavior so that the nock and vanes avoid hitting the bow (which his large feathers do NOT do) is a function of TUNING, selecting the right spine as it relates to the archer's release technique, the weight of the bow, the point weight, even the nature of the limbs of the bow and the surface of the archer's finger tab.

Earl D Yates Thanks Destin! While I hope that these Scientists are able to find a way to stop the spread of this disease, there are some far reaching implications. This is the first time that I've ever heard of a cancer that is contagious. If a strain of cancer can become communicable among Tasmanian Devils, there is a possibility that some strain of cancer could mutate and become contagious between humans. So, helping to find a cure for these rare critters may in turn, help to prevent a similar outbreak among the human species.
