Stones Have Been Popping Out of People Who Ride Roller Coasters
Using centripetal force to prevent a $4 billion healthcare cost
By James Hamblin

1. Doctor finds anecdotal evidence that people are passing kidney stones after riding on Big Thunder Mountain Railroad at Disney World

2. Doctor makes 3-D model of kidney, complete with stones and urine (his own), takes it on Big Thunder Mountain Railroad 60 times

3. “The stones passed 63.89 percent of the time while the kidneys were in the back of the car. When they were in the front, the passage rate was only 16.67 percent. That’s based on only 60 rides on a single coaster, and Wartinger guards his excitement in the journal article: ‘Preliminary study findings support the anecdotal evidence that a ride on a moderate-intensity roller coaster could benefit some patients with small kidney stones.’”

4. “Some rides are going to be more advantageous for some patients than other rides. So I wouldn’t say that the only ride that helps you pass stones is Big Thunder Mountain. That’s grossly inaccurate.”

5. “His advice for now: If you know you have a stone that’s smaller than five millimeters, riding a series of roller coasters could help you pass that stone before it gets to an obstructive size and either causes debilitating colic or requires a $10,000 procedure to try and break it up. And even once a stone is broken up using shock waves, tiny fragments and “dust” remain that need to be passed. The coaster could help with that, too.”

SCIENCE: IT WORKS

Sorry RWBY fans, this isn’t RWBY related, but it fits my blog. My family 3D printed a container for me, that has the digits of Pi swirled up it. It’s super cool, I like Pi, and fits my blogs name, lifeofthreepointonefour.

Here’s What Actually Happens Inside Our Lunar Lab

Water is a precious resource – especially on the Moon! In the near future, robotic rovers may roam the Moon’s poles in search of hidden reservoirs of water beneath the lunar surface. But traversing the poles can be a perilous journey. Depending on the Sun’s position in the sky and the way that its light falls on the surface, hazards such as boulders and craters can be difficult, if not impossible, to see. 

Inside our Lunar Lab at Ames Research Center, researchers are using Hollywood light kits and a giant sandbox filled with 8 tons of artificial Moon dirt to simulate driving conditions at the poles. The research aims to provide rovers and their human supervisors with 3-D hazard maps of the Moon’s terrain, helping them to avoid potential obstacles that lie ahead. 

Here’s how it works:

STEP 1: GENERATE A MOON MAP

Researchers begin with a map of the Moon’s terrain that’s randomly generated by a computer. Each scene is based on observations made from lunar orbit. The map indicates the number, location and size of features like rocks and craters that should be placed inside the 12x12-foot testbed.

STEP 2: BUILD A MOONSCAPE

Using the map as a guide, researchers build the terrain by hand with everyday tools. The terrain is then dusted with a top layer of artificial Moon dirt to eliminate shovel and brush marks.

STEP 3: CAPTURE IMAGES

Lights are positioned at different locations around the testbed. One by one, the lights are switched on and off while a camera captures images of the terrain. Notice how the appearance of the terrain changes depending on the source of illumination.

STEP 4: CREATE A 3-D MODEL

Using a computer algorithm, a 3-D hazard detection model of the terrain is generated from the images. The model provides important information about the size of an obstacle, its height and where it’s located.

STEP 5: GO EXPLORING

With this technique, researchers can teach a rover to recognize the effect of different lighting conditions on the Moon’s poles. The tool could come in handy for future lunar rover missions like Resource Prospector, which will use a drill to search for subsurface water and other compounds on the Moon.

Studying Storms from Air and Space

Technology we’ve developed is helping study the movement of storms.  

From satellites that can slice through a hurricane with 3-D vision to computer models of gale force winds, scientists now have unprecedented ways of viewing extreme weather.

This August, we’re sending an unmanned aircraft called a Global Hawk to study hurricanes. This mission is called the “East Pacific Origins and Characteristics of Hurricanes,” or EPOCH. It will fly over developing tropical storms to investigate how they progress and intensify. 

The three instruments aboard this Global Hawk aircraft will map out 3-D patterns of temperature, pressure, humidity, precipitation and wind speed as well as the role of the East Pacific Ocean in global cyclone formation. These measurements will help scientists better understand the processes that control storm intensity and the role of the East Pacific Ocean in global cyclone formation.

To better understand hurricane formation and intensity, scientists also utilize models and other observations.

Satellites such as our Global Precipitation Measurement Mission, or GPM, and computer models can analyze key stages of storm intensification.  

In September 2016, GPM captured Hurricane Matthew’s development from a Category 1 to Category 5 hurricane in less than 24 hours.  

Extreme rainfall was seen in several stages of the storm, causing significant flooding and landslides when it passed by Cuba, Haiti and the Dominican Republic.

By combining model and observed data, scientists can analyze storms like never before. They can also better understand how hurricanes and other powerful storms can potentially impact society.

Solar System: Things to Know This Week

From images to virtual reality and interactive simulations, NASA offers plenty of ways to explore our solar system – and beyond – in 3-D.

1. Step One: Get the Glasses

Many of the images and interactive features require special glasses with red and blue lenses.

2. Breaking News (Virtual Reality Edition)

Big news from 40 light-years away (235 trillion miles). Our Spitzer Space Telescope revealed the first known system of seven Earth-size planets around a single star. Three of these planets are firmly located in the habitable zone, all of them have the potential for water on their surfaces.

No glasses required.

This image was created by combining two images from STEREO B (Feb. 24, 2008) taken about 12 hours apart, during which the sun’s rotation provides sufficient perspective to create a nice 3-D effect.

3. Free-Range 3-D Exploration

Our Eyes on the Solar System app allows free exploration of Earth, our Solar System and thousands of worlds discovered orbiting distant stars. And, you also can explore it all in 3-D!

Under visual controls just check 3-D, pop on your glasses and explore.

4. Your Star in 3-D

The STEREO (Solar TErrestrial RElations Observatory) mission studied the sun in 3-D with twin satellites.

5. National Parks in 3-D

The Earth-orbiting Terra satellite’s Multiangle Imaging SpectroRadiometer (MISR) instrument provides 3-D views while orbiting Earth, including some great shots of our National Parks.

6. Get in the Pilot’s Seat

Take a look inside the cockpit of our high altitude ER-2 aircraft as it descends for landing at Kaneohe Bay, Hawaii. This month, scientists used used the aircraft to collect data on coral reef health and volcanic emissions and eruptions. Flying at 65,000 feet, above 95 percent of Earth’s atmosphere, the ER-2 has a unique ability to replicate the data a future satellite could collect. Data from this mission will help in developing a planned NASA satellite mission to study natural hazards and ecosystems called Hyperspectral Infrared Imager, or HyspIRI.

7. Moon Views

The Lunar Reconnaissance Orbiter creates 3-D images from orbit by taking an image of the moon from one angle on one orbit and a different angle on a separate orbit.

This stereo scene looking back at where Curiosity crossed a dune at “Dingo Gap” combines several exposures taken by the Navigation Camera (Navcam) high on the rover’s mast.

8. Martian 3D

Our Mars fleet of rovers and orbiters captures the Red Planet from all angles - often in 3-D.

9. Saturn in 3-D

The Cassini spacecraft’s mission to Saturn is well-known for its stunning images of the planet and its complex system of rings and moons. Now you can see some of them in 3-D.

10. Want More? Do It Yourself!

Put a new dimension to your vacation photos. Our Mars team created this handy how-to guide to making your own eye-popping 3-D images.

BONUS: Printer-Friendly

Why stop with images? The Ames Research Center hosts a vast collection of 3-D printable models ranging from the moon craters to spacecraft.

Slytherin: I know you already have a plan. And I want to win, so for the next eight hours, I’m down with all your nerdy crap. Come on, Ravenclaw. Show me the binder.
Ravenclaw: Okay, but it’s not a binder. It’s a virtual binder, and it’s encrypted on this flash drive.
Slytherin: That’s my girl. Now, where’s the 3-D model of the precinct?
Ravenclaw: Inside the keychain. It’s a frickin’ hologram.

So uh… my husband is kind of the greatest? He’s not an artsy kinda guy (a scientist by trade) but he spent a few weeks learning how to use 3-D modeling software so that he could take models from MGS1, tidy them up (there were a lot of shortcuts taken to save polygons and processing power) and created this amazing figure for me!!! I now have this beautiful one of a kind Otasune Ending commemerative figure on my Metal Gear shelf and I absolutely love it!

New Mass Effect: Andromeda Rumors

So I’m sure that by now, even people who aren’t fans of Mass Efffect are aware of the latest game’s facial animation issues, and many fans of the series have been asking “How could a massive AAA game with millions of dollars and years of development time shit the bed so hard on such an important part of the game?”

Well, it may not have been the fault of the development team, and the blame can instead be laid at the feet of Upper Management at BioWare.

Liam Robertson AKA Game History Guy over on YouTube made this video on the subject. This is all stuff that should be taken with a grain of salt, and may not be entirely true, but it is all certainly plausible. For anyoen who is unable or doesn’t have the time to watch the entire video, here are the key points.

According to his source at BioWare, the reason the animations are so bad is due to the use of CyberScan technology, which can scan a person into the game and create a high-quality model of the person, however, the technology is not to the point where it alone can create a model all on its own, and the 3-D model it creates then needs to be sent to an animator, but it is a fantastic tool for creating a base to work on.

After the Cyberscan Process was complete, instead of letting the game’s development team work on it, the human character models were instead outsourced to various development studios associated with EA, no one is quite sure which ones, but it seems that EA Bucharest in Romania did a lot of the work. But the real kicker are the reasons behind this decision.

While business costs are certainly lower in Romania due to a much lower labor cost, that was apparently NOT the reason that this decision was made. The main reason was because Upper Management at BioWare did not consider the facial animations to be enough of a priority for the main dev team to spend time on, in spite of the Development Team insisting otherwise, and instead sent these animations out to various studios, and had the Main team work on Hard Surface Assets like Enviornments and ships, as well as a few robotic characters and some of the aliens.

Also cited as a reason was a “Corporate Culture of Political Correctness” and a fear that the in-house team would make the characters (not just the female characters, but all characters) “too attractive” and alienate some audiences.

If this turns out to be true, then this has got to be a new level of corporate incompetence, deciding that Facial animations and character modeling is unimportant in a heavily story and character-driven game where you will spend a significant amount of time staring directly at those faces and  models and animations has got to be some kind of record for “Worst Decision Ever Made Concerning a Video Game.” This would be like if Blizzard decided to outsource the shooting mechanics in Overwatch to some other studio.

It goes without saying that this all needs to be taken with a grain of salt, but if this is true, then What the Actual Fuck is wrong with BioWare’s upper management.
