Rattlesnake Hill tickets at the Phoenix International Raceway cost a small fraction as much as tickets into the raceway grandstands, but you get a lot more freedom of movement and, I think, a better view. (I've never seen this race from inside the track, so I don't know that for sure.) The tickets allow you into the fence that surrounds the hill. Once there, you can park yourself anyplace on the hill you want, and the only limiting factor is whether somebody beat you to your spot and how high you feel like climbing. Some people set up really elaborate mini-camps with canopies covering grills and buffet layouts marked by flags flying from flagpoles they carried in themselves. Other people just find themselves a rock. You can bring in coolers full of food if you want, but you have to buy your alcohol from an on-site vendor who sells cans of Coors or Miller Lite for $14 each. Unfortunately, the only food they sell is those big pretzels, and I don't really like big pretzels.

Here, you can see a picture I took from the bottom of the hill of Robin about halfway through the race when I went down to buy a couple of $14 Miller Lites. Robin is sitting about 55 feet up the hill (according to Google Earth elevation measurements) on a flat spot along the ATV road that NBC TV people use to haul their camera equipment to the top. (NBC likes to use the hill's summit as a camera vantage point for transitional shots.) This is maybe 20 feet lower than we sat last time, but the hill is steep, and we didn't feel like climbing any more. We bought those umbrellas to attach to our regular camp chairs specifically for this race. She's wearing noise cancelling headphones, because even on a hill outside the track, a NASCAR race is loud. She has earphones inside the headphones, which are connected to a little radio tuned to the race coverage on MRN radio. Our little radios are kind of cheap, and reception wasn't that good. Also, the MRN feed was about five seconds behind reality, but still, it was good enough to keep us in the loop.

Fifth Grade Bake-Off 2017

Boys fossil hunting in the ravines of Fraction Creek in Dellwood Park, Lockport, Illinois.

The November cold-snap hung on in Scotland for that much longer than it did south of the border.

The site is Mossmorran near Cowdenbeath, which Wikipedia says is a NGL (natural gas liquids) fractionation plant, part of the North Sea Brent oil and gas field system.

This is what happens when you get four of your friends to relax their mouths and then shake their heads violently while aiming your camera at them to capture a fraction of a second of the move.

Find an Equivalent Fraction will learn about what are equivalent fractions and how to find an equivalent fraction ? Suppose we are given any fraction say a/b. To find the equivalent fraction for a/b, we will multiply both the numerator and the denominator by the same number. The fraction so obtained is equivalent to the given fraction. In the same way if we go on multiplying the numerator and the denominator of the given fraction by any natural number, we get a series of the fractions which are all equivalent.

The light from early galaxies had a dramatic impact on the gases filling the universe. The stars in these galaxies gave off radiation that ionized the gas (stripping away an electron). This is a supercomputer simulation of this event, called the “epoch of reionization,” which shows where the ionization due to light overwhelms that due to gravity alone.

This visualization highlights the spatial structure of the early galaxies' light's effect, by comparing the ionization fraction from two simulations: one with a self-consistent radiation field (radiative), and one without (non-radiative). The yellow and red regions show where the gas has been ionized in the radiative simulation, while at the center of these blobs are small blue regions where the ionized gas from the non-radiative is concentrated. The purple illustrates the boundary at the advancing edge of the ionization, where the two simulations are the same.

We were shopping on the oldest shopping street in North America Rue d'Champlain with our daughter in law & son and I was finding a few more fraction street numbers.
