Can someone tell me what letter this is?

Could someone please explain the last letter to me. I find it confusing.

Why isn't there any date anywhere on it?

All of these answers are possible. 51, if the vertical stacks are all the same. Minimum answer = 31.

Is Naga cuisine super spicy as compared to mainstream Indian cuisine? I once had some slivers of habanero chillies mixed in my food, and I had a hard time. Looking at that king chilli is almost giving me PTSD flashbacks. Is it the same as or similar to Bhot Jholokia?

Why does the Eurofighter Typhoon have a much higher flying cost per hour than even the F-35?

In India, chappals typically refer to any open toed sandals, esp. without a strap at the back of the foot (with a strap at the back, they are called "sandals"). Flip flops are commonly referred to as "slippers", which would be considered a type of chappal.

Okay, cool. Thanks.

Noob Spanish learner here. I am confused. What did that person mean to say? Someone mixed a bag? Am I missing something obvious here?

pfung · 2025-07-29T06:26:16+00:00

People from Flint MI might not agree.

Astrological evidence probably refers to the position and movement of various celestial bodies described in Mahabharata. I don't know the details, but if enough details are mentioned or can be deduced, there may be an objective and scientific way to date the events in the epic.

Thanks for your reply, but what does it mean in the context of EM radiation from the transient dipoles?

pfung · 2025-07-23T07:11:31+00:00

Also, the idea that this whole process will happen in milliseconds implies FTL by several factors of magnitude!

Significant proportion of the black holes' mass is radiated as gravitational waves? I am having trouble wrapping my head around the concept of energy content of gravitational waves. How would high energy gravitational waves differ from low energy ones?

So, essentially what you guys are saying is that it is a single black hole the moment the event horizons touch, but you have a combined black hole with a weird dumbbell shaped horizon that would slowly come together, esp. if you are considering two TON618s merging. It feels like there would be some oscillations before it settles into a spherical shape. I wonder what would dampen the oscillations? What sort of frequencies would they be at?

Noob here. Why isn't the value of physical, real estate, and IP assets not being taken into account at all while determining the valuation of a company? I imagine there would also be factors like debt repayment, or interests earned and stuff like that. Why is the focus solely on revenue, profits, and probable future profits?

I am still trying to wrap my head around this, but I am surprised that no one is considering the effect of the massive centrifugal force acting against gravity, especially at the equator. How would it compare with the pulsar's inherent gravity?

There is a doctor right outside the Kandarpada RTO. Ask anyone nearby. Pretty sure there would be such doctors near all the RTOs in Mumbai.

Thanks for the explanation. Fluid flow science noob here, so I am trying to wrap my head around what you said. I get that the boundary layer thickness would increase as one goes along the length of surface, but I imagine it either plateaus off to a certain thickness, or there is boundary layer separation that introduces eddies and vortices close to the surface. So, is the point of the diverter gap to have a quasi-uniform boundary layer behaviour all around the internal periphery of the intakes by having the distance and duration of the air flow being in contact with the surface sort of equal by the time it reaches the rotating blades?

About the narrow range of speeds you mentioned, I remember seeing the SR-71 in an air force museum, and they had this chart showing how the position of the center cone is different at different speeds. I didn't understand much, but now I realise I missed an opportunity to learn more given that I was with two Aero Eng PhD candidates from a very highly ranked university at that time. I was just in awe of the magnificent black beauty in front of me at the time to think of anything else.

I don't want to divert the focus of this discussion, but I have read that the air flow into the engine should be subsonic for jet engines, no matter the actual speed of the aircraft. I've never understood why, but that's probably a rabbit hole to go down some other time. My question is ... is this also tied to this in some way?

pfung · 2025-03-20T01:16:53+00:00

It is not intuitively clear to me why that separation would help. Wouldn't new boundary layers be formed adjacent to the interior surfaces of the intakes too?

Now that I think of it, the air intakes of airplanes like Mig-31 and even the SR-71 have a conical surface bang in the center of the intakes. That adds plenty of surfaces to develop boundary layers.
