This week the world learned more about the U.S. government's use of drones for targeted killings of its opponents.
U.S. news reports disclosed the existence of a remote base in Saudi Arabia that is used to conduct drone attacks in Yemen, something they had known for some time.
NBC News obtained and published a confidential Obama administration memo that argues it has the right to carry out the extrajudicial killing of American citizens.
Use the interactive below to learn more about the history of drone strikes.
I was wrong. Conor McGregor vs. Floyd Maywather is happening. It’ll take place on August 26 in Las Vegas. I never expected the deal to get done and I thought we’d all wasted the last year talking about it. But, somehow, someway, it got done. Credit to all parties involved.
As you can see from the tweet above, Conor is already in troll mode. Don’t expect Floyd to sit back while Conor throws his verbal jabs. The build-up to this bout will be extraordinary as both men are charismatic and outspoken. It’s going to draw at least 3 million pay-per-view buys. But will it be competitive? I have my doubts. Money is currently rolling for McGregor, but that’s because he was such a heavy underdog that people felt the risk was worth it. As the fight gets closed, Mayweather should be a huge favorite.
When something like this gets announced, Twitter just has to weigh in.
The last tweet is my favorite. There’s actually a stipulation in the contract that says “Conor can’t do MMA stuff in a boxing fight.” Conor didn’t get to where he’s at by being dumb. He was never going to throw a kick or go for a takedown. But I like that Floyd thought enough of it that he made sure to put it in the contract.
The fight is over two months away, so get ready for an endless amount of talk about it before the inevitable disappointment.
What causes the phase difference between electric and magnetic fields of an EM wave in a conductor?
When an EM wave travels inside a conductor, we find that there is a phase difference between the Electric and magnetic fields within the conductor. The magnetic field lags behind the E field and this lag is roughly equal to 45 degrees within a good conductor (all from Griffiths chp 9.4). What is the cause of this phase difference though? If an EM wave is incident on a lossless dielectric and then travels within that dielectric, the transmitted electric and magnetic waves are in phase with each other as they travel through/inside the dielectric medium. But if an EM wave is incident on a conductor, the transmitted wave travelling within that conductor ends up having a phase difference between its electric and magnetic fields.
I know that in a driven LR circuit there is a phase difference ($\phi_o $) between the driving voltage and the current through the inductor. Since the magnetic field produced by an inductor is proportional to the current, we know that there is an equal phase ($\phi_o$) difference between the driving voltage and the magnetic field produced by the circuit. Is this phase difference in any way related to the phase difference we get when an EM wave travels in a conductor?
The inductance is essentially zero, so not that same mechanism.
But since it’s not an inductor, that removes both aspects of your statement - i.e. does not just eliminate the 90-deg phase difference, but also the fact that magnetic field is proportional to current.
Remember that because of high conductance ($\sigma=\frac{1}{r}$ so $\sigma / \omega >>\epsilon_0$), we ignored the effect of $\frac{\partial E_x}{\partial t}$.

DC vs CSK Playing 11 Playing 11 prediction, IPL 2021: Delhi Capitals and Chennai Super Kings will face-off in IPL 2021 today. Know, with which playing XI both can go.
DC vs CSK Playing 11 Today Match: The 50th match of IPL 2021 will be played between Delhi Capitals (DC) and Chennai Super Kings (CSK) on Monday. This is the 13th match between DC and CSK in the current season. At the same time, in the second phase, DC will take the field for the fifth time and Chennai for the sixth time. Delhi has 18 points from 12 matches after 9 wins and 3 losses and is in second place. Chennai is at the top with 18 points from the same number of matches. CSK also suffered three defeats, but the MS Dhoni-led team is on top due to a better run rate.

Whose upper hand in Delhi-Chennai?
Delhi and Chennai will face each other for the second time in IPL-14. Earlier, when the two had a collision, Delhi had defeated Chennai's team by 7 wickets. Now CSK will be trying to avenge this defeat. At the same time, if we talk about the 24 matches played in the IPL between both the teams, then CSK has the upper hand. Chennai won 15 matches while Delhi tasted victory 9 times. However, DC dominated the last five matches of both. Delhi could win 3 and Chennai could win in 2 matches.
Delhi Capitals beat Mumbai Indians by 4 wickets in their last match. DC's top order did not perform as per the expectations but the bowlers made a tremendous impression. Despite this, the winning combination of Delhi is unlikely to change. On the other hand, Chennai suffered a crushing 7-wicket defeat at the hands of the Rajasthan Royals in the previous match. Dhoni Brigade had given a target of 190 runs but his bowlers could not defend. CSK had rested all-rounder Dwayne Bravo and pacer Deepak Chahar in the match against Rajasthan, but both of them may return to the playing XI after the loss.
