We understand new things by putting them against what we already know—the differences and similarities that emerge help us grasp details in ways that abstract definitions often can't.
So for this list, we've compiled a set of funny, bizarre, and even unsettling comparisons. From everyday objects to cool inventions and rare natural phenomena, each side-by-side photo offers a fresh way to look at the world around us.
There are so many curiosities out there, we just have to open our eyes!

Bald Eagle Size vs. Grey Wolf, Caught On Trail Cam
The scientific term for analyzing new ideas by placing them beside something familiar is analogical thinking.
Psychologist Dedre Gentner's structure-mapping research shows analogies work because people map relational patterns between a known "base" and an unknown "target," not merely surface similarities. That relational mapping is what lets a learner transfer understanding from one domain to another.

Gentner herself often uses the classic analogy of flowing water compared to electrical circuits.
In the "base" domain of water flow, water moves through pipes under pressure from water towers or elevation. In the "target" domain of electricity, electrical current flows through wires driven by voltage (electrical pressure).
Despite the differences—pipes vs. wires, water vs. electrons—the relational structure is the same, and it's that shared relational schema that makes the analogy meaningful.

Education researchers have put this into practice. Studies and systematic reviews of classroom work find that analogies, especially when visual or explicitly mapped out, help learners anchor abstract scientific concepts in everyday experience.
Teachers commonly use images, textual cues, and audiovisual aids to compare known and unknown domains, and these strategies are associated with improved comprehension when used methodically.

Smoker vs. Non Smoker
quentariel 3 months ago (edited)
Smoker who never cleans their windows. My grandpa smoked inside, but always when we visited, he cleaned everything and aired for days (and of course smoked at balcony). There was never visible signs of smoking in his apartment, and the smell wasn't really overpowering after all the effort. Smoking inside (or smoking anyway) is not a good thing, but it is possibly to keep the effects kinda in control and not make it obvious it's a smoker's apartment.

These days some cancers can be maintained at a certain stage and not get worse. I hope that is the case for you.❤️

It could be that but… it could also be UV from the sun reacting with the type of plastic used for the blinds (photooxidation). UV light can yellow certain plastics. My upstairs blinds are different than the rest of the house and as a result that one set is no longer white but has yellowed similar to these.

Pyla 3 months ago (edited)
You are looking south/southeast over the Columbia River gorge. The reason there are trees obscuring the view at the bottom is due to strict regulations on keeping the area green and pristine. Lots of contention, but they seek to protect its legacy from houses taking over.

Our Chicken Eggs Before And After Free Ranging
Grundel County 3 months ago
Darker yolks come from diet, not free ranging, though free ranging may offer the opportunity for wider variety of foods for the hens to nibble on, thus picking up the extra vitamins and nutrients required for a dark yolk. However, if hens have access to certain foods (lots of bugs, leafy greens, etc...) even in a fenced area without free range access, the yolks will also be this dark orange color. Source- ive had a bunch of chickens for a bunch of years and in the winter when they're all cooped up (hens hate their feet touching snow) i give them certain foods to produce produce eggs with yolks of this color.
