Why Touch Screens Only Respond to Fingers: The Science Behind the Sensitivity

  I. Introduction Touch screen technology enables direct interaction with devices through touch. Using either capacitive or resistive methods, these screens detect user input, translating it into commands. Widely used in smartphones, tablets, and kiosks, touch screens offer intuitive navigation, eliminating the need for physical buttons and enhancing user experience across various applications. Understanding how touch screens work is crucial for users and developers alike. It enhances user experience by ensuring effective interaction, informs choices in device selection, and guides troubleshooting. For developers, knowledge of touch technology is vital for creating intuitive applications and improving interface design, ultimately leading to greater user satisfaction. This blog aims to explore why touch screens predominantly respond to fingers, delving into the science behind touch sensitivity. By examining the principles of capacitive and resistive technology, we will uncover the

Echoes of the Past

It was 2 AM at Vijayawada railway station when I briefly regained consciousness, disturbed by the sounds around me. A family entered my compartment—parents and two kids. I couldn't fall asleep again until they settled down. Finally, I drifted off, lulled by the rhythm of the train's movement.

My ears perked up and my eyes flew open when someone said, "Pinky, you can sleep now in the lower berth; I'm going to the middle one." My mind raced, urging me to look at her. Was it really the same girl I wanted to erase from my memory, yet somehow couldn't? Yes, it was her—the very same, unchanged since I last saw her at her wedding.

Eleven years of togetherness had crumbled in an instant because I refused to beg her parents for our marriage. They say love is blind, but love can be incredibly selfish too. Imagine if your loved one turned down a proposal from a celebrity just for you; that day, I became the joker in a match that was never meant to be.

She left me behind, and that day I decided to channel my heartbreak into ambition. I poured myself into work, aiming to outshine Arpit, Pinky's husband. Now, seven years after our formal separation, my company, Mechoz Edutech, is thriving—an educational chain with an annual turnover of 50 crore.

As I lay there, I felt the urge to catch her attention, curious to have a conversation. I got off the upper berth, went to the bathroom, then returned, pretending to be half-asleep. She noticed me, of course; girls have an uncanny ability to read subtle cues.

We both loved train journeys. I remembered the trip on September 20, 2010, when we headed to Goa for her birthday. We shared earplugs, listening to music on the Samsung Android I had gifted her the previous Valentine’s Day, immersing ourselves in the characters of every song.

A few minutes later, my phone beeped with a text: "Is that you?" I considered replying "no," but our relationship wasn't light enough for that anymore. I replied, "Yes."

Pinky: "You’ve become Golu Motu."

Me: "No change in you."

Pinky: "Really?"

Me: smiley 😉😉

For ten minutes, our phones fell silent, and we stole glances at each other, careful to avoid eye contact.

Then my phone beeped again—this time, it was a WhatsApp message.

Pinky: "Follow me." It was 3:30 AM.

We met near the entry gate. A chaiwala approached us, asking if we wanted coffee. At that hour, a hot cup of coffee felt like winning Rs. 100 in a phone transaction.

For a couple of minutes, we stood in silence. I broke the ice by asking how life was treating her.

"Good," she replied firmly.

Me: "Going fast—two kids in seven years."

She smiled. "Congratulations on becoming rich!"

I was surprised she still seemed so simple.

Pinky: "Are you alone? Family?"

Me: "Hey, are you mad? I’m still single—right where you left me."

The day she turned away from us, I decided to empty the space she’d occupied in my heart.

Just then, someone approached and asked Pinky, "Who are you talking to?"

Pinky: "Didi, he’s my childhood friend."

Lady: "Oh, is that Dev? I’ve seen you on Pinky’s timeline."

Pinky: "Dev, this is Namita didi, Arpit's first wife—and my co-wife."

My blood ran cold. I was taken aback.

"How do you manage this?" I asked, still in shock.

Pinky: "No surprises, Dev. We have a formal agreement. I take care of the kids and do research. Thanks to Nami didi, I completed my PhD and published thirteen research papers."

Namita: "Alright, you both keep talking," she said, stepping away.

I expected Pinky to invite me in for a deeper conversation.

As we approached Visakhapatnam station, I said I needed to get off. Before leaving, I asked, "Pinky, why didn’t you reach out to me?"

Pinky: "I feel like I cheated you."

Me: "It’s okay. There’s nothing wrong with staying in touch. You still have me tucked away in your heart."

Pinky: "What? How can you say that?"

Me: "That ring on your middle finger tells the whole story—the one I gifted you."

Top 5 technical skills that will be on demand in 2021

If we can’t see the world behind the mountain does not mean it ends up there probably we don’t put effort to climb up and visualize the existence. In extension to this we may say there is no job scarcity in India but the skill gap is. Companies are eying on the professionals who suits best to bridge their requirement.   Here are 10 top technical skills in-demand we should focus on. 1.     Artificial Intelligence(AI) 2.   Cloud computing 3.    Data Analytics 4.     Internet of Things (IOT) 5.   Virtual Reality (VR ) 1.      Artificial Intelligence(AI): As per the survey of the world economic forum, artificial intelligence will create 133 million new jobs by 2025. It also is expected that the machines will do more work than the humans by 2025.   Artificial intelligence refers to the way a machine can easily mimic humans and execute tasks precisely even if it’s more complex. AI is continuously evolving as a most suitable aid for many different industries. The expectations in future from A

Reviving the past: Mercury arc rectifiers in modern engineering

  I.                     Introduction: An electrical device that transforms alternating current (AC) into direct current (DC) is called a mercury arc rectifier. It works on the basis of the mercury arc valve principle, which depends on how mercury vapor responds to an electric field. In 1902, Peter Cooper Hewitt created the mercury arc rectifier, which was used to transmit high-voltage direct current power as well as to power motors, transmissions, electric cars, and trains. Before the invention of semiconductor rectifiers like diodes and thyristors, this was the first way of high power rectification. Mercury-arc rectifiers were almost completely replaced by semiconductor rectifiers after their creation because of their lower price, improved dependability, easier maintenance, and decreased risk to the environment. Researchers have brought back this old technology. II.                   The rise of mercury arc Rectifiers: Here's how obsolete technologies like mercury arc

Pressure measurement, Pressure transducers, Lecture Note on Pressure transducers

Introduction: The pressure exerted by a static fluid depends only upon the depth of the fluid, the density of the fluid, and the acceleration of gravity. Mathematically,  P = ρgh Static and Dynamic Pressure:   Static pressure: At any point in the fluid, the small chunk of fluid experiences the same pressure from all direction and this pressure is called static pressure. Dynamic pressure: In a fluid flow the stagnation of flow results in conversion of kinetic energy into an additional pressure on the surface which is called as dynamic pressure. When a flat plate is kept against the flow, the fluid is stagnated and creates an additional pressure on the plate which is called as stagnated pressure. Stagnated pressure= Dynamic pressure + static pressure Dynamic pressure= Stagnated pressure - static pressure Pressure measuring transducer:  Often pressure is measured by transducing its effect to a deflection through use of a pressurized area and either a gravitational or elastic
