La Misericordia es uno de los mas bellos rstros del Amor de Dios

Ellas Lo Dicen–Casados, ¿pero Preparados? [Ep.11 2017]
El Matrimonio es un sacramento bellísimo que conlleva, al mismo tiempo que bendiciones, responsabilidades de las cuales es necesario estar consciente para asumirlo en su totalidad. La necesidad de prepararse para el sacramento del matrimonio.

If you love the Top Wing theme song and show opener, you're going to really shake your tail feathers over remixed versions of it! You can find full episodes of ‘Top Wing’ weekday mornings on Nickelodeon, and everywhere you find Nick Jr.

If you know Penny, Swift, Brody, and Rod, then chances are you know the Top Wing theme song! You'll get to hear the theme song remixed in some wacky ways, and you'll get to see changes to the show opener! One version includes animal sound effects, while another has Rod rockin’ out, or clucking out, a solo! The show opener is also altered, so kids can watch it upside down or just with Brody jumping over Penny! Watch all 9 super silly versions and tell us which version you think tops them all!

To relax. To disconnect from the tentacles of 24/7 technology. To truly unplug. It’s become more than a goal. It’s become a necessity. And, it’s become more difficult than ever to do, especially when we sleep. Essential to one’s complete physical, emotion and mental health, the deeper and more tranquil sleep, the better. The answer to those better nights lies with music.

Think of the baby and the lullaby; how the gentle sounds, almost instinctively, hypnotically induce a calming, soothing state ideal for sleeping. Slower rhythms with soft sonic edges, played at a consistent volume, encourage deep relaxation, blocking out distractions, and helping the body to quickly find and maintain its natural sleep rhythm. Music is the medicine.

Chronic sleep problems can be physically draining, and turn what should be hours of blissful escape into anxiety-ridden nightly recurrences. Set aside the daily grind and unwind with music designed specifically to promote soothing dream states, and provide more rejuvenation in the morning. Not to mention the proven benefits of lower heart rate and lower blood pressure, reduced insomnia, and increased energy the next day.

It’s time to fall asleep faster, wake-up less, and feel more rested in the morning. It’s time for Music For Sleep.

Every day in an adult human roughly 50-70 billion of your cells die. They may be damaged, stressed, or just plain old - this is normal, in fact it’s called programmed cell death.

To make up for that loss, right now, inside your body, billions of cells are dividing, creating new cells.

And cell division, also called mitosis, requires an army of tiny molecular machines.DNA is a good place to start - the double helix molecule that we always talk about.

This is a scientifically accurate depiction of DNA. If you unwind the two strands you can see that each has a sugar phosphate backbone connected to the sequence of nucleic acid base pairs, known by the letters A,T,G, and C.

Now the strands run in opposite directions, which is important when you go to copy DNA. Copying DNA is one of the first steps in cell division. Here the two strands of DNA are being unwound and separated by the tiny blue molecular machine called helicase.
It literally spins as fast as a jet engine! The strand of DNA on the right has its complimentary strand assembled continuously but the other strand is more complicated because it runs in the opposite direction.
So it must be looped out with its compliment strand assembled in reverse, section by section. At the end of this process you have two identical DNA molecules, each one a few centimeters long but just a couple nanometers wide.

To prevent the DNA from becoming a tangled mess, it is wrapped around proteins called a histones, forming a nucleosome.
These nucleosomes are bundled together into a fiber known as chromatin, which is further looped and coiled to form a chromosome, one of the largest molecular structures in your body.
You can actually see chromosomes under a microscope in dividing cells - only then do they take on their characteristic shape.

The process of dividing the cell takes around an hour in mammals. This footage is from a time lapse. You can see how the chromosomes line up on the equator of the cell. When everything is right they are pulled apart into the two new daughter cells, each one containing an identical copy of DNA.
As simple as it looks, this process is incredibly complicated and requires even more fascinating molecular machines to accomplish it. Let’s look at a single chromosome. One chromosome consists of two sausage-shaped chromatids - containing the identical copies of DNA made earlier. Each chromatid is attached to microtubule fibers, which guide and help align them in the correct position. The microtubules are connected to the chromatid at the kinetochore, here colored red.
The kinetochore consists of hundreds of proteins working together to achieve multiple objectives - it’s one of the most sophisticated molecular mechanisms inside your body. The kinetochore is central to the successful separation of the chromatids. It creates a dynamic connection between the chromosome and the microtubules. For a reason no one’s yet been able to figure out, the microtubules are constantly being built at one end and deconstructed at the other.
While the chromosome is still getting ready, the kinetochore sends out a chemical stop signal to the rest of the cell, shown here by the red molecules, basically saying this chromosome is not yet ready to divide
The kinetochore also mechanically senses tension. When the tension is just right and the position and attachment are correct all the proteins get ready, shown here by turning green.
At this point the stop signal broadcasting system is not switched off. Instead it is literally carried away from the kinetochore down the microtubules by a dynein motor. This is really what it looks like. It has long ‘legs’ so it can avoid obstacles and step over the kinesins, molecular motors walking the other direction.

Compliant mechanisms have lots of advantages over traditional devices. SimpliSafe is awesome security. It's really effective, easy to use, and the price is great. Check out SimpliSafe here: https://simplisafe.com/veritasium

I visited the Compliant Mechanisms Research group at Brigham Young University and spoke to Professor Larry Howell:
https://www.compliantmechanisms.byu.edu

At the above link, you can download 3D-print files to make some of the objects in the video, plus learn more about compliant mechanisms.

What I learned about compliant mechanisms I summarize in the 8 P's of compliant mechanisms:

1. Part count (reduced by having flexible parts instead of springs, hinges)
2. Productions processes (many, new, different enabled by compliant designs)
3. Price (reduced by fewer parts and different production processes)
4. Precise Motion (no backlash, less wear, friction)
5. Performance (no outgassing, doesn't require lubricant)
6. Proportions (reduced through different production processes)
7. Portability (lightweight due to simpler, reduced part count designs)
8. Predictability (devices are reliable over a long period of time)

To celebrate the announcement of the discovery of a particle consistent with the Higgs Boson at the LHC, I took to the streets with Vi Hart to give out free Higgs. Now giving out a subatomic particle, especially the Higgs, would have been incredibly difficult so instead we gave out hand-drawn cards of the Standard Model, our current best theory of all matter particles in the universe and their iteractions (now with Higgs!). We also offered a hug with an integer spin, usually 1 or 2 (and in rare cases 0). This is a way of showing others that you care about the Higgs Boson.
