That Dahlia photo got my wife's attention (she is into colored-pencil artwork and wants to try sketching it).

After a bit of on-line research she came up with:
Sorry, no URL; she is on a tablet and can't display such 'unimportant' things! It was found thru a Google search for Dahlia Mary Eveline. The following came up when she clicked on one of the first few sponsored advertising images.

Call name: Dahlia Anemone Mary Eveline (some American sites use Evelyn)
(Scientific)
Name: Dahlia
Species: Dahlia
Genus: Dahlia
Family: Asteraceae
Order: Asterales
Hardiness: Zones 8-11
Duration: Perennial
Sun exposure: Full Shade
Soil: Loam, Sand, Clay
Soil PH: 6.1-7.5
Thanks a lot! :smile:

I got some help stringing together a series of images into a video, the idea is a continuous zoom. Hope you enjoy it!

Fun Easter Egg! What are the black rectangles around the IC? They look too fine-pitch to be wire bonding pads...?

If I understand what you mean, those are indeed the bonding pads... I don't think there were actual wires, tho-not sure what the correct terminology is for modern stuff (bump bonding?)

Pretty amazing stuff. One of the previous companies I worked for did advanced IC packaging, but I was only peripherally involved in that part of the business. Looking it up now, I guess it is indeed possible...

https://semiengineering.com/scaling-bump-pitches-in-advanced-packaging/

1689700325666.png


Interconnects for advanced packaging are at a crossroads as an assortment of new package types are pushing further into the mainstream, with some vendors opting to extend the traditional bump approaches while others roll out new ones to replace them.

The goal in all cases is to ensure signal integrity between components in IC packages as the volume of data being processed increases. But as devices continue to shrink and more components are added into advanced packages to process, move, and store more data, new technologies with more I/Os will be required. So while traditional solder balls and/or copper microbumps still will be used for the foreseeable future, new technologies are under development that can augment or replace those interconnect technologies, increasing the number of I/Os and providing more headroom for scaling.

As always, size and cost are the determining factors. Copper microbumps are smaller than solder balls/bumps, enabling more I/Os in packages. In today’s advanced packages, the most advanced microbumps involve a 40μm pitch, which equates to 20μm to 25μm bump sizes with 15μm spacing between the adjacent bumps on the die.

Probably hard to find in cheap, small versions, though... :smile:

Here's one listed, though I somehow don't think it's the real thing :biggrin::

The low price is matched by the low magnification! (from site: Magnification ratio: 50X-1000X)

It's practically an electron mAcroscope!

That's an optical microscope mislabeled as an electron microscope by some stupid marketer, probably it is electronic and he got confused.

Even the smallest EMs (electron microscopes) take a table top. And yes, they do require a vacuum (those electrons have to be able to fly free).
They also require high voltages (not usually available at home) and a very vibration free install site.
Scanning EMs look at surfaces and are probably the smallest.
Transmission EMs (electrons going through sections) are larger and often higher power.

My favorite photo, when I was studying their work they always seemed bigger than life. But when I look at this, I try to see them as average people and not as the rock stars of physics. I know a bit about some of their personal lives but not much. I have to think their egos were huge! I tend to think an evening with that crowd would not be easy.

I would expect a variety of personalities. it wouldn't surprise if certain types were disproportionately common, but not exclusive.
I haven't know a lot of physicists, but I have known many biologists. Some are quite nice. Some have won Noble Prizes.
Some are assholes, not all do well.

If you could meet one person from that photo today, who would it be?

For me it would probably be Schrodinger. From what I have read he liked the ladies. I do too so we would probably have a lot to talk about. :cool:

It might be fun to talk with Heisenberg about the philosophical implications of his uncertainty principle. But what physicist or physics lover could resist an opportunity to speak with any of them?!

Here's a post about a little editing trick in Photoshop...

I took a walk through the park the other day and saw a nice scene, but I didn't have my system camera with me, so I shot it with my mobile phone which doesn't happen very often these days.

What caught my eye was the sky and the reflection of it in the pond.
If I had been using my system camera I would have shot it with a polarizing filter in front of the lens to get a more dramatic contrast of the sky, but I had to do without it.

Here's the original:

1.png


In Photoshop you can use can use the Shadows/Highlights adjustment (Menu->Image->Adjustments->Shadows->Highlights) and set it like this...

Image-Adjustments-Shadows-Highlights.png


...which can give a more dramatic sky.
This is a kind of "overexposure compensation".
Another little trick I picked up from somewhere I don't remember.

Here's the edited result:

The colors change a bit, but this can of course be further edited if you like to.

Here is a map of South Asia (land of the Danios) and their drainage basins. I got it from this place.
The drainage basins are a common restriction for where a species can easily spread to.
There are several isolated drainage basins in Tibet and Mongolia with no outlet to the sea.

Are they launching a new degree program in beekeeping?

Are they trying to raise money to pay off their loan from the US Department of Agriculture?

Are they pollinating the campus flower beds?

Are the bees supposed to go after intruders?

Was there a telephone mixup when they tried to book a Beyoncé concert?

No, none of the above... the state beekeepers' association is holding its annual meeting here!

Unless some of her children were twins or triplets, she would have been pregnant for 51.75 years.
69 children x 0.75 years per pregnancy = 51.75 years pregnant.

Based on a wild guess of the radios in the foreground currently costing 2.5 times the posted price, I get around 1985.

Based on my (vague) memory of store layout and clothing style, mid-to-late 1970's.
