#17-2

Local spotting also included Ft worth Alliance airport KAFW and during the right time we can get some interesting subjects such as F/A-18, UH-60, F-5n and of course we get the usual trainers from Sheppard, Laughlin, Columbus , Randolph whereby in a good weekend we can get up to 30 trainers at a time with assortment of T-38C, T6, J1 and T45.

For Military Exercise we get to cover Red Flag Alaska 17-2 in Eielson AFB and this Exercise include the full Pacific Air Force units including 25th FS, 35th FS, from Osan AB, 13th and 14th FS from Misawa AB, 107th FS A-10 from Michigan ANG , Japanese Self defense Air Force F-15MJ and Republic of Korea Air Force KF-16D units. We also cover Dawn Blitz Exercise in Southern California where we get to photograph on board USS Essex.

Our Airshow coverage for 2017 was widespread , they include local shows like Lancaster airport war bird flyin, Ft worth Alliance Airshow,  Travis AFB, Capitol Airshow and the French aerobatic team Patrouille Acrobatique de France USA tour, Tinker AFB Airshow in Oklahoma. Wings Over Houston, Joint Base San Antonio Airshow, Nellis AFB Aviation Nation. International Airshow coverage include Royal International Air Tattoo “RIAT”, Jesolo airshow in Italy and Athens Flying Week.

Overall we have a very busy year in 2017 and we are looking forward for 2018 with more military aviation coverage. Thanks everyone for the support and see you next year.

This is the 2nd video of however many videos I’ll be making this year to better document the inherent weirdness that is 17. 

There’s a lot of slow motion, a lot of time lapses, and a lot of bad color grading, which I think is all of the ingredients you need to make a good video.  However, what seems to have happened is that I got the amounts all messed up.  I knew I shouldn’t have tried to double the recipe without double checking the measurements. 

RATES OF CHEMICAL REACTIONS

-Measure the loss of reactant of the appearance of product

-collision theory: for a reaction to occur, reactants must

i.) collide

ii.) collide with enough energy

iii.) collide with the right orientation (the right bits need to hit each other. No use hitting the wrong side of the molecule)

-reactions are spend up by

i.) increasing temperature because it increases the number of collisions and energy of collisions

ii.) increasing concentrationg of reactants because it causes an increase in number of collisions

iii.) increasing surface area because it increases the number of collisions

iv.) adding a catalyst

-collisions are only effective if they are with neough energy called the activation energy of Ea

(diagramn like this picture)

they need to collide with enough energy of they don't react. Ea is the energy required.

-If you increase the temperature, the highest point of the graph will be further right and so more particles will be over the Ea.

-So you need to add more energy so they can collide with more energy

Before something can react, it will need a little bit more energy. We're used to graphs of exothermic reactions looking like this but they really look like this. That bump is called the 'activated complex'. It is an in-between stage. If it loses energy, it can go back to its proginal state. If it gains a little more, it can cross over into being a product.

A catalyst lowers the Ea, therefore more particles will have enough energy to react. It provides an alternate pathway, but it is not part of the collision.

E.g. (this is just too funny so i had to write it down). Lily wants her foot to react with Ellie's elbow, making a footbow. She needs to have enough energy to kick Ellie's elbow off, and then connect her foot with it.

Tamara is a catalyst. She chops off people's elbows. So Lily can just go around reacting with elbows the Tamara has chopped off, without needing the extra energy to kick them off.

Tamara is not part of the reaction. She is not a product or a reactant. She'll go around chopping people's elbows off, and if you put her into another classroom she'll just chop all their elbows off too. All she does is aid the reaction.
