Coordinated Energy Weapons

2021-01-01T02:30:00.000-08:00

The Greek mathematician Archimedes may have impacted the world forever more than 2,000 years prior as the principal individual to actually utilize a coordinated energy weapon. As indicated by a baffling legend, during the Roman intrusion of Syracuse, Archimedes quickly built a hexagonal mirror when the Roman naval commander Marcellus moved his boats out of the scope of bowshot.

Archimedes was evidently ready to catch the energy of the Sun and reflect it onto the boats, setting them on fire and making them sink inside minutes.[1] MIT understudies had the option to reproduce this impact in 2005 yet noticed that their mirror was just able to do successfully consuming a fixed objective.

Despite the fact that logical information has progressed an extraordinary arrangement since the times of Archimedes, the basic hypothetical standards of coordinated energy weapon (DEW) innovation continue as before. A DEW exacts harm from a distance by terminating a seriously thought light emission toward an objective.

Various sorts of DEWs shoot various kinds of energy, however the most promoted type of coordinated energy weapon being used today is the high energy laser (HEL). These DEWs are much the same as the lasers found in sci-fi motion pictures. They fire a soundless light emission, imperceptible at specific frequencies, that can burn an objective from many miles away.

HELs have been developed by contractors like Lockheed Martin for use in missile defense and space war, but some believe that these weapons might have been designed with much more sinister purposes in mind.During the Thomas Fire that ravaged California in December 2017, many witnesses and researchers noted property damage that seemingly defied every preconceived notion of how a wildfire should behave. Though wildfires use foliage to spread, entire blocks of houses burned to the ground while the surrounding trees remained untouched.Though no official explanation of this anomalous phenomenon is forthcoming, multiple witnesses across California recorded video of beams of light coming down from the sky as the blaze spread across the state. Given the fact that HELs are commonly mounted on the nose cones of planes, some have concluded that the mayhem wreaked by the Thomas Fire was boosted with directed energy weaponry.

Usage of Have, Has been, Had been

2018-11-20T23:38:00.000-08:00

When to use: to have

I have a new car. The basic meaning of the verb have is “to be in the possession of something”. It is used in present simple, and it expresses a fact of having something in the present. When it comes to auxiliary verb “have”, we use it to form present perfect and present perfect continuous. I have gone to that show already. In this example, “have” is used as an auxiliary verb to form present perfect. Present perfect is a tense that connects past and the present. In this example, the person went to the show sometime in the past, but that is still valid in the present. Auxiliary verb “to have” is used to express that present through its present form. I have skipped breakfast today and now I’m hungry. In this example “have” is again used to form present perfect. Here it expresses a finished action in the past that has a result on the present – because the person in the example didn’t eat breakfast in the morning, in the present the person is hungry. To connect the two, present perfect is used and the verb “have” again serves as a signal of the present time by being in the present itself (by form). I have been going to the same cafe for 10 years. Auxiliary verb “to have” is also used to form present perfect continuous. The tense is used to express regularity of some action that started in the past, and continues to happen throughout some amount of time regularly and it is still true in the present. Auxiliary verb helps us to become aware of the present time of the action. I have been watching that show the whole day. In this example have is also used to form present perfect continuous. It expresses and action that started in the past, but was happening the whole time leading up to the present, and continues still. The present form of have reminds us of the present time of the action.

When to use Has been?

That china set has been in our family for year. In this example, we see another form of the verb “to have”. “Has” is the third person singular of the verb to have, used for pronouns he, she, it. In this example, we used it to form present perfect, and has functions the same as “have” – it contains and expresses the present time, connects the past and the present. He has been reading for the past two hours. In this example has is used to form present perfect continuous. It is used for the same pronouns, he, she or it, so, for the third person singular. As we said, as have and has are the same verbs, their function is the same – has also signaled the present for some action that started in the past, but continues up to the present. She has been running for half an hour without any pause. Has is again used to form present perfect continuous. It expresses an unfinished action that started up in the past continued to happen for some amount of time leading up to the present and is still true in the present.

When to use had been?

I had a dress like that, I don’t know where it is now. Verb “had” is the past form of the verb to have. It expresses the possession of something in the past, something someone had before, but no longer has, the action is completely in the past. He had studied English before he moved to New York. “Had” may also be used as an auxiliary verb to form past perfect. When we use past perfect, we express a past action that happened before some other past action, so past before the past. Auxiliary verb “had” signals the past by it past form. When it comes to had, it has the same form throughout all persons, so with he, she, it, we also use “had”, just like with all other person. I had gone to that school before I changed cities. In this example we are again faced with a past action that happened before some other past action. To express that, auxiliary verb “had” is used. He had been waiting there for more than 2 hours when she finally arrived. Auxiliary verb “had” is also used to form past perfect continuous. It expresses some past action that was happening for some time in the past, before some other past action happened. To sum up, we use auxiliary verb “have” to form present perfect and present perfect continuous. “Had” is the past form of “have”, and therefore it is used to form past perfect and past perfect continuous.
