“Why Teach Science When You Can Just Fill the Time with Glue and Glitter?” Ah, science education. Once the proud torchbearer of reason, discovery, and curiosity, now just a meandering parade of pre-made models, marshmallow-and-toothpick molecules, and baking soda volcanoes. If we wanted students to really think, we’d have them staring at blank walls, not gluing spaghetti to cardboard. But alas, it seems science education is now a creative arts class in disguise—minus any of the creativity. Gone are the days when students would be introduced to real, gritty concepts like the laws of thermodynamics or the elegant nuances of quantum mechanics. Instead, we hand them pre-cut pieces of plastic for “build-your-own-DNA” kits. What better way to spark scientific interest than following an IKEA-like instruction manual for “learning”? It’s hard work, pretending that pressing play on the latest 3D cell animation video is “teaching.” And let’s not forget the pièce de résistance: the model of the solar system. Not because they’re learning the incredible forces at play but because, apparently, what the science curriculum really needs is… Styrofoam balls in orbit. Perhaps, someday, science education will move beyond time fillers and half-baked projects. But until then, we’ll keep the glue and glitter companies in business. #ScienceEducation #EdSatire #STEM #RealLearning #CriticalThinking #FutureScientists #BeyondTheClassroom #InnovationInEducation

Main research project: a light and easy way to describe a vibration pattern, then we can evaluate the stability of robot movement. But the side projects are more interesting: 1. How does light spectrum affect neurons growth 2. A microscopic fingerprint for art painting 3. A locker to deny LLM tokenizing your knowledge content without your permission

Quantity vs Quality …!!!

The invention of the Gutenberg press in the 15th century marked a turning point in human history, revolutionising the way information was produced, disseminated and consumed. Its profound impact on education, culture and communication laid the groundwork for the modern knowledge-based society. The Gutenberg press was invented by Johannes Gutenberg around 1440 in Mainz, Germany. At the time, Europe was experiencing a cultural and intellectual revival known as the Renaissance. However, knowledge was still largely restricted to the elite due to the limited availability of books, which were laboriously hand-copied or produced using rudimentary woodblock printing. Gutenberg sought to address this issue by creating a method to produce books quickly, cheaply, and in large quantities. Gutenberg combined existing technologies, such as the screw press, with his innovation: movable metal type. This allowed for reusable letters and symbols to be arranged into different texts, making the printing process far more efficient. His first major project, the Gutenberg Bible (1455), demonstrated the potential of his invention. The press significantly increased the production speed of books, reducing the cost and making them more accessible. By lowering the cost of books, literacy rates improved, and ideas spread more rapidly. Texts became more uniform and reliable, reducing errors found in hand-copied manuscripts. The press facilitated the dissemination of Renaissance, Reformation, and Enlightenment ideas. It laid the groundwork for newspapers, magazines, and other printed media, influencing political, scientific and cultural development. The Gutenberg press emerged at a time when Europe was transitioning from the medieval era into a more connected period. Increased trade and urbanisation created a growing demand for knowledge and education. Additionally, the Catholic Church’s dominance in intellectual life was being challenged, leading to movements like the Protestant Reformation. The printing press played a crucial role in amplifying Martin Luther’s ideas, making it an essential tool for societal transformation. Without the Gutenberg press, the world would likely have progressed at a much slower pace. The rapid spread of scientific discoveries, political ideas, and cultural works that the press enabled would have been delayed. Education might have remained a privilege of the elite, perpetuating inequalities in access to knowledge. Movements like the Enlightenment and industrial revolutions could have been postponed, altering the course of history. The Gutenberg press is often regarded as one of the most significant inventions in history. By democratizing knowledge, it reshaped societies and laid the foundation for the modern world. Its legacy is evident today, from printed books to digital media, underscoring the importance of Gutenberg’s impact of making religious texts accessible, making books widely available, improving literacy and spreading knowledge.?

?? Print media is NOT dead. When studying in-depth, I still print papers out. Your comprehension isn't the same with a screen and 1000 distractions. Studies have shown that comprehension improves with print media use and writing notes vs typing. In this case, I'm preparing for my Blast-RADIUS presentation by reviewing this 18 page paper. The CWAP book stays on my desk as a reference when answering support engineer questions. My eyes were struggling when I already stare at screens for hours each day. Printing the study out made highlighting and adding my own notes much easier. This habit goes back to my SUNY Purchase intern days. We printed out relevant studies to our research and took notes the same way. I also helped make a robotic arm, but that's a story for a different day. ?? Are you studying for an important test? Try printing notes or writing them by hand. The studies: https://lnkd.in/dvh3NhGv https://lnkd.in/dKs8RtAS

Do you create new projects just to teach yourself new skills? I've done this since I was a teen in the late 1980s. I'm a strong proponent of project-based learning. One of my current projects is a video-based recreation of my graduate research defense in 2001 at the end of my Masters of Science degree in Applied Physics from the UNC Charlotte Department of Physics and Optical Science at the University of North Carolina at Charlotte. I know what many former #graduateStudents in the audience are thinking: why would you rehash your silly masters defense? Again, it's my playground to learn and refine some new skills while also helping to build a portfolio of my work. The content already exists, and I want to learn some new media skills. Here is a short video I finished that includes the original #PowerPoint animations I created as part of my presentation in 2001. Back then, I had just begun using PowerPoint #animations and had included all the animations you'll see in this 80 second video on a SINGLE SLIDE using multiple graphic layers to hide subsequent elements of the animation. Back then, I had to tap the ENTER key to advance to each animation. In the last week, I've decomposed the original file (presented in the dated but classic 3:4 aspect ratio) into EIGHT individual slides and exported the fully automated animation (no more key tapping for me!) to a video format. The video format was then edited with sound and narration clips using the VSDC Video Editor. I created the audio clips myself using Audacity and recorded narration with VSDC Voice Recorder. The video shows the processing steps use to fabricate a patterned oxide film on a #silicon wafer in today's more expansive widescreen 9:16 aspect ratio. This is one small part of the fabrication process I used to study a new method to fabricate heavily p-doped films in silicon by diffusing atoms of silicon through a metal aluminum film and growing the silicon epitaxially at a buried aluminum-silicon or aluminum-oxide interface. One technology this work may have been useful for is Silicon-on-Insulator (#SOI) using standard CMOS processing of local SOI regions. Another use of this work is the p-junction in a #MOSFET (transistor). I haven't yet gotten to the more modern #FINFET (transistor) fabrication, but with nanoprocessing techniques and tools, it would be a lot of fun to play in this new sand box while testing many ideas I've developed over the years. What sort of projects have you created for yourself to give yourself the opportunity to learn and develop new skills?

Analogical Thinking: Analogical thinking is a cognitive process that involves drawing comparisons between two different things based on their similarities in some respect. This type of thinking is crucial for problem-solving, creativity, and learning because it allows individuals to transfer knowledge from one domain (the source) to another (the target). Following are the key aspects of Analogical Thinking: 1. Identification of Similarities: Involves recognizing a relationship in one context and finding a similar pattern in another context. 2. Problem Solving: People can apply solutions from familiar situations to new or complex problems. For instance, using the analogy of water flowing through pipes to understand electrical circuits. 3. Learning and Transfer: Analogies help in understanding new concepts by relating them to already known ideas. 4. Creativity: Many creative breakthroughs arise from seeing connections between seemingly unrelated ideas. For example, the invention of the airplane was inspired by the way birds fly. 5. Communication: Analogies are powerful tools in communication, helping to explain ideas in a way that is more relatable and understandable to others. Some examples of Analogical Thinking: A. Comparing the structure of an atom to a solar system. B. Describing a computer virus as similar to a biological virus. C.
