Has everyone forgotten about LUVOIR?

I remember hearing about it years ago, around 2015–2016, while I was also hearing about JWST. I spent years waiting for JWST, and then finally watched the launch live on NASA’s YouTube channel in 2021.

Then I thought: Okay, JWST is finally up. Now LUVOIR is the next big one.

But then... nothing.

It's 2026 now and I realized I haven't heard anything about LUVOIR in years.

Turns out I wasn't waiting for a delayed LUVOIR launch.

LUVOIR basically evolved into the Habitable Worlds Observatory (HWO)

I genuinely thought I'd eventually get to watch a giant telescope called LUVOIR launch after following it for a decade haha

I know this is a very random request, but I figured this would be the best place to ask.

I'm really interested in seeing a video of someone handling a vial of dimethylmercury. It's a strange combination of chemistry curiosity and the unsettling feeling of watching someone work with one of the most dangerous substances ever used in a laboratory.

Does anyone know if such a video exists, or has it simply never been publicly recorded?

Hi everyone,

I recently turned 18 and am currently in my final year of high school. I do not have any source of income at the moment.

Electronics has been a passion of mine for years, especially designing and building circuits. Over the past few weeks, I saved up and convinced my parents to let me buy around ₹700 worth of components for learning and experimenting. I am very grateful that they agreed to that.

Unfortunately, I realized that I am still missing one essential part to complete my current project: three LM370 voltage regulator ICs, which cost ₹134 (approximately US$1.60).

I cannot ask my parents for more money because they have already spent more than they were comfortable with on the earlier components, and I understand their decision.

I know this is not a necessity compared to many other requests here, and I completely understand if people choose to prioritize others. However, if anyone is willing to help me with ₹134 (approximately US$1.60) so I can order the remaining ICs and finish my project, I would be incredibly grateful.

Financial situation:

- Final-year high school student

- No income

- Not receiving any government assistance or benefits

If anyone is able to help, I can only accept an Amazon.in gift card, as I plan to use it to purchase the components directly from Amazon India.

Thank you for taking the time to read my post, whether or not you are able to help.

So I know attendance dosen't matter,

But till today (25th Jun 2026) I have gone to school literally only ONCE.

(Private school)

I was thinking about a conceptual issue in basic circuit theory and wanted to clarify the meaning of “equipotential” more rigorously.

Consider two points A and B connected by an ideal wire in a battery-resistor DC circuit. We often say the wire is equipotential, meaning V ᴀ = V ʙ , so Δ V = 0 along the wire segment.

My confusion arises from the following reasoning:

If V ᴀ = V ʙ , then ∇ V = 0 along the wire, so E = 0. Using J = σ E, it seems like current density inside that segment should be zero.

But in a steady-state circuit, we know current is nonzero everywhere in the loop, including through that wire segment. This leads to an apparent contradiction:

- If the wire is truly equipotential, does that imply no current flows between A and B?

- If current does flow, does that mean the wire cannot be strictly equipotential?

- And if current exists while E = 0, how is continuity maintained without any “jump” in current at the resistor?

I’m trying to understand precisely how “equipotential wire” is defined without conflicting with current continuity.

It was an old Android Bomberman style game from around 2012–2013.

What I remember:

- retro/pixel graphics

- top down Bomberman gameplay

- anime/chibi style characters

- one unlockable anime girl character

- instead of placing bombs normally, her special ability created flame explosions directly from her body

- may have had something related to sheep in the title/icon/theme/mascot

- definitely on Android

- old APK era mobile game

- offline game

The game was NOT modern looking and had a very old school retro style

Does anyone remember this?
