Here is a summary of the questions which has possibly been set wrong (I have given details below) or numerical answer types whose answers have been given incorrectly as per the declared answer sheet.
Q8. The magnetic field also has a odd parity. Not “E and A only”. Since that choice (or “none of the above”) isn’t given, clearly the question has been set wrong. See here.
Q3. The Stern-Gerlach experiment evidenced space quantification of angular momentum. The Zeeman effect evidenced the existence of electron spin. That choice isn’t given, instead answer sheet gives the opposite as the correct answer. See any good text on quantum mechanics. eg “Quantum Mechanics 2nd edition, Bransden, Joachain” page: 37 and 38. To avoid any ambiguity, Its the S-G experiment which evidences space quantization (of both spin and orbital angular momentum). But Zeeman effect evidences electron spin only. It was the anomalous Zeeman effect which had led to the discovery of electron spin.
There are also two NAT type questions which seems to be way off in the correct responses as per the exam conducting body. But the calculations shows somebody missed something somewhere. They are questions 48 and 49 according to the uploaded answer sheet and question paper. I have performed the detailed calculations in this pdf file: gatephysics_2018.
Altogether this is 6 marks and 2/3 marks for the Q3 and Q8 if they have been deducted wrongly. So, 6+2/3 marks. I haven’t been able to find any more lapses although it was very tempting to feel so.
The concurrent election in Odisha just drew to a close and I did an analysis on the results available tentatively. Notice that there is no visible errors here even if I eg adjusted 854 to 850 and so on. If you add up the % figures they add to 100% perfectly — I simply did the calculation and applied no tricks, that means there is some simple pattern in the data which is the reason I made this post.

Are younger generations opposed to Capitalism? This is a guest post by Sabuj, who writes with much clarity on Quora and I thought this is interesting enough to be shared on this website. He also writes voluminously about various issues of his interest. Since he is very young, it throws a particularly refreshing view into limelight and I would urge you to read this and comment and importantly share this if you liked this. I also invite anyone interested to make a wider audience of his/her interests in creative writing connected to academics (such as science, philosophy, history and sociology in regards to science, cutting edge research and conceptual innovations etc but this is not to say this is the end of the list) can send me a link of his/her article or email me the write up to email@example.com. I would be glad to publish it here if its devoid of any basic concerns and encourage you to suggest a good writer of science, sociology, philosophy etc to contact me, who wants to write here occasionally or regularly. This is not a paycheck generator so you may as well get an unhindered interface to the wider world. (No its not a commercial website as of this moment or any closely seen future ) Its sole aim is to bring the new and fresh to the widows of the inspired world.
Here is Sabuj’s Article. I hope you all enjoy it.
Let me answer this as someone from the “younger generation”. To begin with, your assumption is incorrect. Today’s generation is not completely against capitalism – at least not against the spirit that an individual should be able to benefit economically in exchange of and in proportion to his/her services to the world. We couldn’t even dream of the revolution in information technology and software engineering without capitalism. I am sure your friends do use the products and services which are the outcome of capitalism for the ease of their lives, even though they may be critics of capitalism itself. More…
The quality of a scientific paper are not ZERO if citation is zero. Perhaps we need to define two parameters, quality and significance of scientific communication. Quality; a well done research in the best traditions and methods available. Significance; the outreach of the paper to bring effect into others work and others understanding toward the subject matter.
While there will always be a downside to both parameters, citation reflects the significance (and quality as much as it correlated to significance) of a paper. More…
Here is the summary. And I am quoting actual numbers from News Paper Reports.
News Report; 5% Odisha Resident students. [Including perhaps those also who would be Odia by their citizenship, irrespective of where they stay]
My estimate; a typical 10% general category students, going by how large the quota regime entails in terms of percentage toward quota qualifiers.
News Paper Report; Lying vacant per anum, 10%.
My reasoning; if there would be no quota based qualification system perhaps these seats would never lay vacant, plus we would have far superior engineers produced in the country. Because the 3-levels of quota scrutiny sees the merit off to such a level even 10% seats lay vacant, at the same level that gets admitted after fierce scrutiny. More…
