![]() Then, in August 1984, McAuliffe saw a headline in the local paper reading, “Reagan Wants Teacher in Space.” She occasionally had students dress in period costumes. She would bring her guitar to class and strum ’60s protest songs. She was an engaging and well-liked teacher. In 1983, she landed her “dream job,” teaching social studies at Concord High School. She attended Framingham State College, and in 1970, she married her former high school boyfriend Steve McAuliffe. “But she wouldn’t have made much of an astronaut anyway,” Cook writes, “a chubby Girl Scout with no knack for science or math who got sick to her stomach on carnival rides.” McNair likely struggled in vain to prevent their doom after surviving the initial shuttle explosion.

She idolized John Kennedy for his push to the moon, and as a seventh-grader in 1961, she watched Alan Shepherd become the first American in space. Growing up in Framingham, Mass., young Christa Corrigan was always fascinated by space. Instead, she ended up as arguably the most well-known name in America’s worst space-related tragedy. She was meant to be the first civilian in space, a fearless woman who set out to prove that “teachers have the right stuff, too,” as one of McAuliffe’s friends put it in the book. McAuliffe, 37, was a Concord, NH, social studies teacher who had won NASA’s Teacher in Space contest and earned a spot on the Jan. 28, 1986, mission as a payload specialist. The brave crew members - Smith, Dick Scobee, Ronald McNair, Ellison Onizuka, Judith Resnik, Gregory Jarvis and Christa McAuliffe - survived the initial disaster and “were conscious, at least at first, and fully aware that something was wrong,” author Kevin Cook writes in the new book “ The Burning Blue: The Untold Story of Christa McAuliffe and NASA’s Challenger” (Henry Holt and Co.), out now. It was ejected in the explosion, and remained intact. Inside Houston’s Mission Control and Florida’s Launch Control centers, rows of S’s lined computer screens, indicating “static.” All audio and communication from the shuttle had been lost.īut the capsule the crew was sitting inside did not explode. A little-known Air Force official whose title was range safety officer quickly hit a self-destruct button, causing the boosters to explode and fall into the sea rather than on any populated areas. The booster rockets separated, and kept blasting upward on diverging paths. McAuliffe was selected out of 11,000 applicants partly because of her ease on camera. The tank quickly ruptured, igniting the hydrogen fuel and causing a massive, Hindenburg-like explosion. The breach allowed a few grams of superheated fuel to burn through.Īt one minute and 12 seconds after liftoff, the small flame grew, taking only three seconds to penetrate the fuel tank’s aluminum skin. The rings failed to expand fully in the cold, leaving a gap of less than a millimeter between booster sections. It was leaking fuel.Īs was later learned, the cold of the Florida morning had stiffened the rubber O-rings that held the booster sections together, containing the explosive fuel inside. Sitting on the right side of the flight deck, Smith looked out his window and likely saw a flash of vapor or a fire.ĭown on the ground at Mission Control, a computer screen indicated falling pressure in the right booster rocket.

Es verdad que hay ciertos principios que uno puede aplicar. The expressions es cierto que, it is true that, es obvio que, it is obvious that, es verdad que, it is true that, and es evidente que, it is evident that are exceptions since they are followed by the indicative and not by the subjunctive. It is very nice that they speak both languages. Here is a list of common expressions of emotion with which the subjunctive is found in the subordinate clause: me gusta que A very common structure that triggers the subjunctive is es + adjective + que expressing opinions. Remember that the subjunctive is found in the subordinate clause of sentences that contain a change of subject from the main clause to the subordinate clause. The subjunctive is used after expressions of emotion and reactions to something. I hope that Spanish becomes maybe another official language in the United States. Here is a list of common verbs expressing will and desire: querer queĮspero que el español se vuelva tal vez otro idioma oficial de los Estados Unidos. The subjunctive is used in dependent clauses after expressions of will, desire, and orders whenever there are two different subjects in the two clauses linked by the subordinating conjunction que. We always danced for her… so that the harvest was good.īecause the subjunctive often occurs in subordinate clauses, the subordinating conjunction que is usually found before the the subjunctive forms. One such expression which is always followed by the subjunctive is para que… so that… Siempre le danzábamos… para que la cosecha fuera buena. It expresses several concepts, such as a wish, hope, or doubt, as well as an obligation or a necessity. It has two simple tenses, present and past (or imperfect), and two compound tenses, present perfect and pluperfect. The subjunctive mood is used more frequently in Spanish than in English.

It might just add the bus you're trying to swap over to, but I'm too cautious to chance having to redo an entire bus line back to normal if they all get added. Other than that, you can look into some open source projects like openttd. Click that to take a bus off shared orders! You can also add running buses to a shared order after they are bough or are running by holding Ctrl and clicking on one of the bus that you want it to share orders with as well! Just make sure that the bus being added isn't already part of another shared order group, otherwise, you might be changing over an entire group. ![]() Got a bunch of already bought buses that are causing jams on a route that used to be busy, but isn't anymore? If the bus already has shared orders and you want to remove them, select the "end of shared orders" section of the list, and you'll notice that the "delete order" option has changed to "Stop Sharing Orders". It will help you to manage stations and vehicles, and will provide you a. ![]() It might also be worthwhile to look into timetables if you want your vehicles spread out evenly. In the end the last line should say 'end of shared orders' instead of 'end of orders'. They will both share that group of orders, and if you were to decide to add or remove a stop to one of the buses who share that order list, it will update for any buses who also share those orders as well! OpenTTD Toolbox is a small app designed to help you when you play Open TTD. Select 'go to' and ctrl click on a train that you want to copy the orders from. If you were to hold Ctrl while clicking during cloning a new bus, you will not only copy it's orders, but will also "link" the cloned bus to the original. Let's say you have a route that has high traffic and you have more than one bus going to and from that area. I don't have here ottd to give you the exact way to share order, but, that's by holding shift or ctrl key (I don't reminder, try both) when you click to 'add order' instead of clicking to a station, click to another train. Also, Don't forget the value and importance of Shared Orders! They are extremely useful! ![]() ![]() ![]()

Such mirrors may have surfaces that are spherical or parabolic. ![]() Specular reflection at a curved surface forms an image which may be magnified or demagnified curved mirrors have optical power. Reflection from a flat surface forms a mirror image, which appears to be reversed from left to right because we compare the image we see to what we would see if we were rotated into the position of the image. This is an important principle in the field of thin-film optics. In contrast, when light reflects off of a material with lower refractive index the reflected light is in phase with the incident light. When light reflects off of a material with higher refractive index than the medium in which is traveling, it undergoes a 180° phase shift. A conventional reflector would be useless as the X-rays would simply pass through the intended reflector. ![]() As the waves interact at low angle with the surface of this tunnel they are reflected toward the focus point (or toward another interaction with the tunnel surface, eventually being directed to the detector at the focus). X-ray telescopes are constructed by creating a converging "tunnel" for the waves. ![]() Total internal reflection is used as a means of focusing waves that cannot effectively be reflected by common means. Total internal reflection of light from a denser medium occurs if the angle of incidence is greater than the critical angle. This is analogous to the way impedance mismatch in an electric circuit causes reflection of signals. Solving Maxwell's equations for a light ray striking a boundary allows the derivation of the Fresnel equations, which can be used to predict how much of the light is reflected, and how much is refracted in a given situation. In the most general case, a certain fraction of the light is reflected from the interface, and the remainder is refracted. In fact, reflection of light may occur whenever light travels from a medium of a given refractive index into a medium with a different refractive index. The law of reflection states that θ i = θ r, or in other words, the angle of incidence equals the angle of reflection. By projecting an imaginary line through point O perpendicular to the mirror, known as the normal, we can measure the angle of incidence, θ i and the angle of reflection, θ r. In the diagram, a light ray PO strikes a vertical mirror at point O, and the reflected ray is OQ. Reflection also occurs at the surface of transparent media, such as water or glass. Reflection is enhanced in metals by suppression of wave propagation beyond their skin depths. Ī mirror provides the most common model for specular light reflection, and typically consists of a glass sheet with a metallic coating where the significant reflection occurs. In specular reflection the phase of the reflected waves depends on the choice of the origin of coordinates, but the relative phase between s and p (TE and TM) polarizations is fixed by the properties of the media and of the interface between them. Reflection of light is either specular (mirror-like) or diffuse (retaining the energy, but losing the image) depending on the nature of the interface. Even hard X-rays and gamma rays can be reflected at shallow angles with special "grazing" mirrors. Reflection of VHF and higher frequencies is important for radio transmission and for radar. Reflection is observed with many types of electromagnetic wave, besides visible light. Reflection is observed with surface waves in bodies of water. In geology, it is important in the study of seismic waves. In acoustics, reflection causes echoes and is used in sonar. The law of reflection says that for specular reflection (for example at a mirror) the angle at which the wave is incident on the surface equals the angle at which it is reflected. ![]() Common examples include the reflection of light, sound and water waves. Reflection is the change in direction of a wavefront at an interface between two different media so that the wavefront returns into the medium from which it originated.
