Do airport X-ray scanners recognize GOLD from other metals in checked luggage?
To make a long story short: for passengers, the airport X-ray scanners employ the back-scatter to reveal the general shape of objects on the surface of human body; for luggage, the scanners employs the similar mechanism as the chest X-ray. Those scanners are not like the clinical CT scanners which provide the cross-sectional images of the patients. It is not possible to use the conventional airport X-ray scanners to identify gold.To tell gold apart from the other types of materials, there are several ways could be done:If one would use a standard CT scanner (i.e. either analytical / clinical types), the incident X-ray spectrum could be adjusted for the k-edge imaging targeted at gold. This method could identify gold even with the presence of some highly absorbing materials (e.g. bone). Of course, a careful calibration of CT number and materials may be necessary.If one would use X-ray scattering tomography, it is also possible to calculate the electron density / effective atomic number distribution inside the objects. Note that the distribution of electron density / effective atomic number is also a great feature for material recognition.If one would use X-ray projections only, it is still possible to recognize some materials. Briefly, one could applied photon counting detector, or applied multi-energy projections. Then, a proper math-physical model could be utilized to decompose the materials.

Which laptop is best for gaming and for professional use?
There is no definitive "best" gaming laptop, it all depends on your use case.If you desire maximum performance but don't care too much about portability, the MSI GT72 and GT80 series are pretty good with lots of RAM, storage, and beefy CPU and GPU configurations. There may be bloat ware slowing the machine down though. Sager and Asus also have offerings in this category. These will generally be the most expensive laptops, ranging from 2000 to 3000 dollars usually.If you just need gaming as cheap as possible, the Acer Predator Helios 300 is a great budget gaming laptop. If you don't want as aggressive a design, Dell offers a gaming line for their Inspiron 7000 and 5000 series. Be sure to check that you are purchasing the correct SKU with the dedicated GPUs.If you want thin and light with the associated price premiums, the Razer Blade (not the Blade Stealth) have excellent build quality, and are extremely light and portable. Not as much as an ultra book mind you, but is a standout amongst its gaming peers. If you need a cheaper alternative, consider the Gigabyte Aero 15X. It's slightly larger and bulkier than the Blade, but is still extremely compact. They also offer Pantone certification for their screen, which features a Dell XPS-like thin bezel, for around 1700–800 dollars compared to the Blade at 2000+Now, there are some extremely high end thin and lights, like the ASUS ROG Zephyrus or the Acer Predator Triton, but they suffer poor battery life, unconventional keyboard trackpad layouts, and a high price of 2700–3000 dollars, and their GPUs are slightly cut down to fit within thermal constraints.

Which laptop will be most suitable to buy in a budget around INR 40-50k?
Well "good configuration" depends on the purpose you are buying the laptop for.You have not put any light on what you expect out of the computer or what are the main tasks you will perform on that computer.Most (not all) of the laptops having screen size below 15" are netbooks that do not offer much powerful processing although they have a great battery life. I have used a netbook having display 10" and it is a pain to use the small cramped keyboard and touchpad. When it came to do heavy task the netbook cried.Remember most of the laptops below 15" do not offer the optical drive facility.Almost all laptop brands now have below 15" laptops in the market. One of the most popular below 15" laptop is Macbook-13",but that will cost you above INR 50K.But there is one powerful alternate (and I think its the best suited for you) that is ThinkPad series by Lenovo. (Earlier ThinkPad were made by IBM). They are less than 15",hardy,offers superb built quality,have powerful processing and have good battery too. Although its looks may not attract you.First check what are the major work you intend to do with the laptop. Then decide on the configuration. Try to take latest configurations so that it helps you in managing for atleast 3 years down the line without much hiccup.If your work is graphics intensive do go for a configuration with dedicated graphics card.And when you have done all the homework go to the market and check out the models and look which model you are comfortable with and matches your requirement. Do this final task extensively.Cheers!
