Microscopes are instruments used to enhance the resolution of an object or image. Types include compound, stereo, or digital. Compound microscopes use a compound optical system with an objective lens and an eyepiece. Stereo microscopes show object depth in a three-dimensional image. Digital microscopes are used to display an image on a monitor, rather than looking through a lens. Microscopes can have monocular (one), binocular (two), or trinocular (three) eyepieces, with varying magnification abilities. Magnification ability refers to the size of an image. Resolution, also known as resolvant power, refers to the clarity of the image. The interaction between field of view (FOV), numerical aperture (NA), and working distance (WD) determines resolution. Microscopes can control magnification through a fixed focus, or through a range of adjustments. They can also utilize LED, fluorescent, and mirror light sources to help control viewing capabilities. Microscopes are widely used in education, lab research, biology, metallurgy, engineering, chemistry, manufacturing, and in the medical, forensic science, and veterinary industries.

United Scope manufactures microscopy equipment and accessories under the brand name AmScope. The company, founded in 1996, is headquartered in Irvine, CA.

Dasksha Chemistry Molecular Model Set your Molecular Model Kit has Perfect Atom and Bond Pieces For Students Teachers Beginners and Experts

The Dashka Chemistry molecular ball and stick model set is for every student, teacher, and organic / inorganic chemistry fanatic. There’s a huge problem schools are facing right now. There is an abundance of cheap models whose short, flimsy links and balls don’t stay in place and fail to conform to universal cpk standards, rendering your molecule structure useless and leaving children of all ages confused and frustrated. Educational classroom models that aren’t color-coded and durable lead to general confusion and failure to grasp concepts. Buying cheap models can cause your understanding of chemical compounds to suffer-and your science grade to suffer even more.

Cheap materials can make trying to easily assemble three-dimensional models of molecules and elements a complete nightmare!

But luckily for you, there’s now a solution to further your understanding of stereochemistry! Whether you’re a beginner in need of a starter kit to better understand fundamental organics and molecular structures, or a college student tackling ochem, the Dashka kit is the perfect functional tool to help you visualize three-dimensional atoms, bonds and compounds.

So, if you’re a student, teacher, or aspiring scientist, “Dashka Chemistry molecular model set” is the answer you’ve been looking for! Time’s running out to make all the three-dimensional models you can dream of and tackle stereochemistry head-on.

The Beginner’s Guide Review — The Shepherd

I’m pretty sure the entire foundation for The Beginner’s Guide is fictional but I know it still manages to be one of the most brutally honest games to have come along in a long time. Coming from The Stanley Parable‘s Davey Wreden, it’s clear this creator trades in honesty. With it, he has delivered one of the most impactful games you can play.

The setup begins rather benign and even exceptionally high concept. (The Steam description even reading more like a warning than an invitation.) Wreden himself bursts onto the audio landscape with a voiceover telling you that he is going to explore a series of games from another developer that is only known as Coda. He’s apparently a friend of Wreden’s and he’s since stopped spinning Source Engine yarns.

Our introduction, in fact, is what appears to be an excised portion from Counter-Strike‘s de_dust or de_dust2 maps. There’s nothing to it but a pseudo desert vibe and strange, floating or half-glitched crates amidst a blocky set of sandy brick walls. You can’t do anything but walk and look around and maybe jump or crouch if you feel the need, and it still feels oddly compelling.

Wreden then takes us chronologically through more of Coda’s odd little experiments, none of them lasting more than a few minutes with most of them phasing in and out in a matter of seconds. Wreden is deconstructing them with nearly criminal, philosophical intent. Here is a fellow who has clearly spent a lot of time playing Coda’s works and thinking about them, breaking down themes and reflections on his relationship with the creator.

Or did he? While plausible, it feels too…neat for Coda and Wreden’s lives to converge and subsequently drift apart as a one-way street of game after game flows into Wreden’s hands. There’s an uneasy similarity of aesthetics between Coda’s projects and Wreden’s. Not only that, but if this were true, it would feel prohibitively invasive to write about it. Needless to say, this review is a bit of a leap of faith in that regard.

But either way, Wreden’s analysis of Coda’s games is gripping. It starts almost clinical, like a doctoral thesis and he is in the middle of his two-hour defense. This, in and of itself, is a fascinating practice. Just the concept of having a developer break down and walk and talk through another’s lifetime of works is impossibly tantalizing.

The Beginner's Guide

Then it slowly descends into a personal, psychological inquiry. It’s especially revealing when Wreden leads us through a set of prison levels, an idea that Coda can’t seem to shake as he explores isolation and loneliness. Wreden has already taken us by the hand and pointed us at perhaps subconscious tells of Coda’s Freudian design schemes, and now we watch it all unravel as this man spirals out of cogency.

The final turn is heartbreaking. After the surprise of what you think the game will be and then what it might turn into before it arrives at what it is deliberate and swift and incredibly affecting. This is where the game feels the most brutally intimate while also feeling the most obviously fabricated.

I actually paused at an open door, waiting for a lump in my throat to decide if it wanted to be tears or a more masculine whimper. It’s a massive credit to the writing of Wreden’s voiceover. It’s economical, pointed, and sharp. At stages, its structure is complex enough to where the bridges between mini resolutions has equally compelling paths leading under it.

The Beginner's Guide

Even disregarding the veracity of Coda’s existence (this very well may turn into an Exit Through the Gift Shop or Catfish situation), the insight this game provides on the relationship between creator and player is paralyzing. There’s a question poised somewhere along the way about whether games necessarily need to be playable, with Coda providing examples of single-room, wholly empty games as playable but uninteresting products.

This invites questions of responsibility and whether either side of the equation owes anything to the other. Wreden turns off the visibility of the walls to one of Coda’s games, revealing that the one corridor you walk through is actually one of hundreds that you can never actually reach. Is it owed to the player to explore those? Should the player even want to?

As Coda begins to extract these out external symbols, Wreden wrestles with the vague semiotics of it all, dipping into the problem of other minds. He stops diving into specifics and we are led more by sensation than by critical thinking. It halts the growth of strict cerebral pleasure and turns into an appreciation.

The Beginner's Guide

It’s not very likely you will have a good time with The Beginner’s Guide. It’s not even likely that you’ll think back on it fondly. But the journey through its blocky walls and Coda’s brain and Wreden’s thoughts is one worth appreciating in the moment, letting it point you around at all the sights worth seeing and all the moments worth experiencing, even when they exist only in someone else’s mind.

+ Emotionally and psychologically impactful
+ Invites great questions regarding creators and players
+ A raw exploration of two minds
– Doesn’t hold up on specifics, working better on broad strokes
