The Science of Airport Security

This machine is either a backscatter X-ray  or millimeter wave scanner.  If the machine just looks like a flat wall,  it’s probably a backscatter X-ray scanner.  These use very small amounts of weak X-rays  that only penetrate your clothes, and don’t  go through your skin.  The machine detects the radiation reflected  by your skin and anything else under your  clothes, and generates an image that easily  shows anything you’re trying to conceal.  The amount of X-ray radiation you’re exposed  to in a backscatter scan is extremely low,  a tiny fraction of the amount you’re about  to be exposed to by flying on a plane.  But still, this technology isn’t used very  often, and it’s banned in many countries.  Instead, millimeter wave scanners are much  more common.  They’re the cylindrical machines that look  like futuristic phone booths, and they use  the same basic principles as backscatter scanners. if you either want to travel to airport select shuttle service

Checking Through X-rays

But instead of X-rays, they emit microwaves,  which are non-ionizing, meaning that they  can’t damage your DNA, and you don’t need  to worry about exposure.  Since millimeter waves can penetrate through  clothing, they can still show if you’re  hiding something that you shouldn’t be.  Once you make it through the scanner though, you might still be in for some follow-up tests.  If security finds anything in your bag  that looks suspicious, they’ll probably  swab you for traces of explosives.  A security officer might swab your hands,  your shoes, or your bag, then place the swab  in yet another machine for analysis.  This is the Explosives Trace Detection machine,  or ETD.  The idea here is that, if you’ve been handling  explosives, or if there were any inside your  bag, the swab will pick up traces of suspicious , compounds.  To analyze the swab, the ETD uses a process  called ion mobility spectrometry.  The machine gives the molecules on the swab  an electric charge, turning them into ions.  Then, a gas carries the ions through a tube.  Different ions will take different amounts  of time to pass through the tube, depending  on things like their mass and charge.  The machine then identifies different compounds  based on how long it took them to move through  the tube.  So, airport security might be tedious and  annoying.  But at least now you know what’s happening  to you and your carry-on.

10 Important Things About Gatwich Airport

If you’re visiting   London and you’re traveling   through Gatwick Airport, here are  some important things  to know before you go.  By the way, if you’re new here, I’m Jess, and I help people who are visiting London  to experience the city like a Londoner,  which is me, I am a Londoner. Gatwick Airport is located  outside of the city.  It’s all the way south of London,  which means that taxis are  actually really expensive  to and from the airport.  There are, however, lots  of transportation options  to get you from the airport to the city,  and for the sake of the  length of this video,  I won’t talk you through all of them,  but you can see all of your options  in my free London 101  Guide, which you can get  by clicking the link in the  description of this video.  There are two terminals, North  Terminal and South Terminal.  It’s really important for you to know  which one you are flying out of,  otherwise you can waste a ton of time,  and there’s a shuttle that will get you  between each of the terminals.  The train station is in South Terminal,  so if you plan on taking  the Gatwick Express  or just the regular train, once you get  out of arrivals, just  follow all the signs.  It’s really well signed, you’ll  be able to find it easily.  You can also buy tickets in the station,  and there’s always staff members there  to help if you have any questions.  You can use your Oyster card  to get to and from the airport.  If you plan on taking the Gatwick Express,  you can use your Oyster card  to pay for your journey,  but I recommend, instead, to  book your ticket in advance  online, ’cause you’ll save  yourself a lot of money.  If you plan to take the  regular train to or from  the airport, it will take it  a little bit longer, but it is  cheaper, and you can use your  Oyster card for that journey.  Head to your gate early.  Gatwick does this thing where they wait  ’til the very last minute to  post your gate for your flight,  so as soon as you see that gate posted,  head to your gate,  because a lot of the gates  at Gatwick take really  long time to get to,  and you don’t wanna find yourself running  to make sure you don’t miss your flight.  There are pay-to-use lounges.  If you aren’t flying business,  or have one of those lounge passes,  you can still book  yourself into one of the  pay-to-use lounges, which  are in each of the terminals.  You can go and try to book yourself in  on the day when you get to the airport,  but I’d recommend booking in advance,  because then you can take advantage  of the premium security  line, and you can also ensure  you actually get a spot in the lounge,  ’cause they do get booked up.  Make sure you have a pen with you on the plane.  If you’re arriving to Gatwick  from a non-EU country,  you’re gonna have to  fill out a landing card,  which they will hand  out to you on the plane.  If you have a pen with you, then you can  fill it out on the plane, and you don’t  have to delay getting on  to the integration line,  which usually gets very long.  Arrive to the airport two or  three hours before your flight.  I’ve never seen Gatwick have long lines at security,  but it’s always best to just  get there nice and early  so you can account for if  you happen to have any delays  on the train, or if the bag  drop line is really long.  (There’s lots to do.  If you arrive to Gatwick early,  you have plenty of  pretty good food options,  plus there’s some  shopping that you can do,  so you won’t be bored as you  wait for your gate to pop up.  And finally, I can’t think of anything  for number 10, so enjoy Gatwick.  If this is your first  time visiting London,  I have a free London 101 Guide,  which tells you everything  you need to know  before you get here, and you can get that  by clicking the card popping  up in the corner here.  Gate early, no, weird  thing with my hands there.  Head to your gate early!  Arrive, everyone’s just like–

How to choose the best and most beautiful beach towel?

Choosing beach towels is not as easy as it seems. Between the models of different sizes, of various colors, made in various materials, it is often difficult to choose. Follow our tips to find the beach towels that best suit your needs.

Beach towels: what size?

When buying a beach towel, the first question that often arises is the size of the towel to take. If you are looking for a napkin for your children, the ideal would be to choose napkins of reasonable size, that is to say that is 86 cm x 160 cm.

A towel of this size is also suitable if you do not want to clutter up during your luggage. For more comfort at the beach, opt for a beach towel of much larger size. This beach towel also called beach towel measures on average 100 cm x 175 cm. By opting for a beach towel of this size, you can be sure that your legs will not rest on the sand once on the beach.

If you are looking for a beach towel capable of accommodating two people at the same time, choose a model whose dimensions are almost similar to that of household linen. This beach towel measures on average 140 x 200 cm. The advantage of this type of beach towel is that outside of the beaches, you can use it as a blanket during picnics or play mats for children.

What material to choose?

Besides the size, the material of the beach towel is another important point to consider when buying a beach towel. The most common models are 100% cotton terry towels. They are soft to the touch and provide soft comfort. The disadvantage of this type of beach towel is that it tends to park the sand, which then becomes quite difficult to remove afterwards.

Microfiber beach towels are ideal, as they are lighter and hardly take up space in a suitcase. In addition, it is very absorbent and dries much more easily than a terry beach towel. However, if you opt for a sponge model, pay attention to the grammage of the sponge. The more important it is, the thicker and fluffier the towel will provide you with better comfort to the touch.

Which color should you prefer?

Admittedly, color is not a decisive criterion in the choice of a beach towel. However, it can change the game between two models with the same characteristics. If you have no idea, choose a towel model whose colors and patterns are reminiscent of the holidays. If you are looking for a beach towel for your children, the ideal would be to choose one whose patterns and shades are reminiscent of the colors of their favorite heroes. Whichever you choose, make sure you like the colors.

Gaming Chairs: A Quick Buyer Guide

we been asked a lot about my chair and whether I still use the Ikea Markus.  And the quick answer is yes but it’s not perfect.  I also have this other generic office chair that was a freebie but it also has its issues.  Why?  Well that’s what I want to cover in the video, so you know exactly what I look for in the perfect task chair for the office.  So let’s start with probably the most overlooked but actually one of the more important feature, the seat pan depth.  When you sit with your back flush against the chair your legs should hang over the edge leaving roughly around 2-3 inches of space between the seat edge and the back of your knees.  If the seat pan is too short your legs don’t get the proper support and if it’s too deep the seat will pinch the back of your legs cutting off circulation.  Some cheaper chairs will have limited seat pan adjustment like this knob here to move the chair back and forth, higher end chairs will usually have more adjustments for this but the ikea markus doesn’t have any so it’s not great for everybody. 

Next let’s look at seat height and this pretty standard on most chairs from cheap to expensive.  You’ll want to set your chair low enough so that your feet are firmly supported by the floor.  And also so that your arms are high enough so your forearms are roughly parallel or slightly downward with the table, while keeping your elbow close to your body.  This does sometimes mean you may need a footrest if your table is too high. 

Why Necessary ?

an adjustable desk like my Ikea so I can adjust it down to proper levels.  Arm rests are another thing I find pretty important especially if you’re sitting for long periods of time.  While not necessary for everyone, at least for me I like to lean on something once in  a while to take the weight off my back.  The arm rests on the Ikea Markus don’t move and are little too low for me too lean on sometimes.  Most other office chairs like my generic one has at least height adjustable arm rests but I still have a problem with these.  I like bring my chair really far forward so my forearms over the table and I can keep my elbows close to my body so I’m not reaching or hunching over.  The issue with typical armrest is even at the lowest setting they can get in way when I try to tuck in my chair in.  High end chairs will sometimes have more adjustments  so you can move them to the back or to the  side so you can avoid this problem or if you  don’t need them you can usually just remove  the arm rests entirely like I did for both  my Ikea Markus and Generic chair.  Everything else I look for in a chair is pretty standard.  Is the seat firm but comfortable?  Check.  Does the chair allow for the back to lean and lock in place when I want a change of position?  Check.  Is the lumbar support in the right position for my comfort?  Pretty good (terrible on my generic chair) Do I need a high back and head rest?  I really like the options.  Will it last for years to come?  Only time will tell but so far so good.

 So in the end what is the perfect chair?  Is the Ikea Markus perfect for me?  Not really but it’s decent for the price.  If you can afford to spend $800 plus on a chair you can look at the Steelcase or Herman Miller chairs that are super customizable and are built to last with long warranties.  And they’re definitely worth it especially if you’re sitting for hours but if you can’t afford them.  Well there are some cheaper options like buying used, or considering models like the Alera Elusion or Office Master OM5.  These look interesting but you often make some sacrifices on adjustability, build quality and warranty as you move down the price ladder.  Or if you’re lucky the Ikea Markus or some other cheap generic office chair could be perfect for you right out of the box.  But in the end you’re going to need test them out in person and check for all the things that I mentioned like seat pan depth, height, and arm adjustments to know what’s best for you.  Hopefully that helps you find your perfect office chair.  You know what to do.

Gaming Chairs: Which model to choose?

When you have so many options it becomes a bit difficult to choose the perfect chair. All have their pros and cons, you just have to find which one best suits your needs.

The best thing you can do before making a purchase is to inform yourself and know the aspects of the chair, so you will avoid investing in a model that may not suit you so much.

In this compilation there are chairs for all kinds of people. If you are looking for a simple but functional model with a good size on the back then the S line is perfect for you, the only detail of these chairs is how firm they are. This may be an advantage for some since not everyone prefers soft padding chairs.

The SL2000 is an ideal model for young people who want a simple and ergonomic model, while the SL4000 is more recommended to an audience that may look for a more comfortable back.

If you are more corpulent than the rest, it is advisable to opt for the models of the P line such as the PL6000 since they have a high weight resistance. However, if you need more space in the seat, the SL5000 is the one indicated.

If you are looking for a unique and easy to maintain chair, the PL4500 is the best. Its coffee strands and silver seams will keep your chair hygienic and free of bacteria. In addition, it is one of the most aesthetic models and you can include the LED light that adds an interesting touch to your gameplay.

If yours is a modern chair, the Triigger 350 outperforms any chair in this compilation. It is extremely light and manufactured with Premium materials. It is the most expensive among all the chairs which may be the main negative aspect of it.

What characteristics are important in a chair?

The price, size, weight support, aesthetics and many other elements are usually the decisive factor of the buyers.

Some factors to take into account in a chair are the wheels and the base. All Vertagear chairs have a star-shaped base that will give you the perfect stability, along with excellent quality wheels.

Another important element is the firmness of the seat, since depending on this we can recognize how durable and comfortable the chair will be. Models that include lumbar support are highly recommended, since by spending so many hours sitting we can develop backaches or numbness. There is no use for a very nice chair but that is uncomfortable, the main thing to look for is the functionality and how adaptable to your body it is.

If you are interested in other high-end chairs, we can recommend you take a look at the DXRacer models, in this review we highlight the most important models.
