Gemini (left) vs ChatGPT vs Claude (right) Prompt: Create... an interactive HTML, CSS, and JavaScript simulation of a satellite system that transmits signals to ground receivers. The simulation should show a satellite orbiting the Earth and periodically sending signals that are received by multiple ground stations. Include realistic factors such as signal delay based on distance, occasional signal loss due to obstructions or interference, and visualization of the signal path as lines or waves. The satellites’ position should be updated using simplified orbital mechanics, and the ground receivers should display received signal strength and timestamps.show more

The physics must remain stable without exploding.show more

🚨 A SATELLITE JUST REVEALED SOMETHING SHOCKING: GPS JAMMING... IS FAR MORE WIDESPREAD THAN ANYONE REALIZED. An experimental navigation satellite called Pulsar-0, flying just 500 km above Earth, has mapped GPS signal tampering from space for the first time and the scale surprised even the engineers who built it. As soon as the satellite passed over Europe and parts of the Middle East, its GPS receiver showed massive signal degradation. In the worst areas, signal strength dropped from a normal 40 decibels all the way down to just 10 decibels. Why this matters: • Ground-based jammers (used in conflicts like Ukraine and the Middle East) are now reaching all the way into low Earth orbit • Satellites like Starlink that rely on GPS for collision avoidance and positioning are being affected across a huge region from France to the borders of Pakistan • When GPS drops out, satellites can’t accurately point their antennas, maintain formation, or safely maneuver • This isn’t just a military problem it threatens the growing network of commercial satellites we increasingly depend on The deeper implication: We’ve long known that GPS signals on the ground can be jammed. What we didn’t fully appreciate is how far those jamming signals reach into space. Even satellites in low Earth orbit the backbone of global communications, Earth observation, and future mega-constellations are now operating in an increasingly hostile electromagnetic environment. Xona’s upcoming constellation aims to fix this with signals 100 times stronger than traditional GPS. But the bigger question remains: as more nations and groups weaponize jamming and spoofing, how resilient will our orbital infrastructure actually be? How concerned are you that GPS jamming is now reaching into space and affecting satellites? Follow for more frontier space technology and the hidden vulnerabilities of our orbital systems.show more

C = εr ε0 (A/d) This demo shows capacitive... coupling using water as a variable dielectric (εᵣ ≈ 80). The human body completes the circuit by touching the water, acting as the second conductor with its capacitance to ground. Hand/finger movement changes the effective area A and distance d, while ripples dynamically modulate C. This varying capacitance alters an oscillator’s frequency, which is converted into audio tones or MIDI in real time. Educational fluid-based sensors and interactive MIDI controllers for bio-signal acquisition and gesture-controlled music. Ideal for physics demos and human-interface experiments.show more

The Coromandel Express, traveling at a speed of 128Kmph,... had the proper authorization to proceed through the mainline, indicated by a green signal. However, someone tampered with the settings and diverted the train to the loop line, where a 6000 tonnes goods train was parked, even though the signal for the mainline remained green. This should not be possible, as India has a robust and world-renowned interlocking system in place. It appears to be a deliberate act of manipulation, suggesting culpable homicide. Such an act cannot be carried out by an individual with no significant influence; rather, it points towards the involvement of major players orchestrating this sabotage. An investigation is imperative to uncover the truth behind this incident.show more

Airbus Vertical Speed Indicators (VSI) primarily use a blended... "baro-inertial" system to display precise vertical speed, combining responsive inertial data from the Inertial Reference System (IRS) with long-term stable barometric pressure data. The inertial signal is used for dynamic maneuvers and air data for stability over time. This hybrid approach provides rapid responsiveness to pitch changes while maintaining accuracy, reducing errors inherent in using either system alone. Local airflow disruptions (such as turbulence or unsteady wind) can momentarily alter the static pressure, causing the VSI to show unsteadiness or oscillations even when the aircraft is on the ground.show more

WHY HAS INDIA SIGNED THE CONDOLENCE BOOK FOR KHAMENEI?... India’s decision to sign the condolence book for Ali Khamenei is being framed as a calibrated diplomatic signal rather than a political endorsement. FS Misri signed on behalf of the government to acknowledge protocol and maintain official channels with Iran, an important regional partner for India. The government describes it as a "graded response, an official level participation, not a political statement of mourning." By keeping the gesture bureaucratic and low key, New Delhi signals respect for diplomatic norms while avoiding a public position on the killing or the wider conflict involving Israel and the United States.show more

🇺🇦🇷🇺 UKRAINE DEPLOYS ROBOTS TO SURVIVE RUSSIAN “KILL-ZONE” In... the hellscape of Pokrovsk, Ukraine is now fighting for survival with ground robots - not just soldiers. Unmanned ground vehicles (UGVs), or “land drones,” are delivering 90% of supplies to frontline troops, dodging Russian drones, artillery, and landmines in a zone so deadly it’s known as “the kill-zone.” Too dangerous for trucks. Too slow on foot. The robots go where humans can’t. Each mission starts in a garage. Ends in life-or-death. One out of three makes it. Welcome to the world’s first robot-supplied battlefield - where survival depends on battery life and signal strength. Source: BBCshow more

❗️🇺🇦🥔 Zelensky warns Belarusian dictator once again: 📌 “Before... taking any public step, I resort to non-public measures for de-escalation. Belarus has received information at the intelligence and military level: stop helping the ‘Russians.’” 📌 “Step number one — no technical support. Turn it off, remove it and show us that it is stopped. Since this has been conveyed to them more than once, we have reached the stage of a public signal. If he does not do this, we will turn everything off (destroy it… hinting at the retranslators used for the wide and uninterrupted dissemination of signals from Russian reconnaissance and kamikaze drones deep into Ukrainian territory).” 📌 “We are also sending a signal: please stop supplying fuel to the Russian army. There is no threat here. We are simply saying that we see this. The first steps are always confidential, while the next steps are different.” Video is generated by Grok AIshow more

If Pakistan is considering adopting the second name, then... a new clause or preamble should be added that reflects both the founder's vision and its civilisational roots. "Pakistan, that is the Indus Valley, is a secular democratic republic based on the principles of liberty, fraternity and equality, as envisioned by its founding father. Pakistan is a spiritual successor to the multi-ethnic, regional and religious cultures it inherited upon its independence as a federation. Economically, Pakistan shall be a social welfare state morally inspired by the Islamic modernist ideals of egalitarianism and equality of mankind. The state of Pakistan shall be referred to as the 'Federation of Pakistan'."show more

Prompt : Epic long shot: An offshore earthquake triggers... a towering tsunami wall. Camera starts in satellite view revealing the wave’s terrifying arc, then drops to a forward-facing ground perspective on a coastal highway. The motorcycle rider appears as a small figure in the distance and charges straight toward the lens, growing rapidly larger as the tsunami races behind them. The camera holds position ahead of the rider (front/three-quarter frontal view), letting the wall of water loom in the background. In the final beats, the rider crests the top level and exits inland onto dry, elevated streets, leaving the surge contained beneath and behind, escaping into safe land.show more

A simplified summary of my simulations of how drone... detector antenna placement affects signal reception, expressed as a conditional drone detection range for different frequencies - obtained roughly by normalizing the square root of total gain to a typical drone detection range. Red line - detection distance for antenna on the roof, blue line - for antenna under the windshield. Considering that the main sector from which drones can approach the vehicle is elevation from 0 to 30 degrees, and also that in reality the glass will attenuate the signal more strongly than in my simulations - mounting the drone detector antennas inside the vehicle significantly reduces its practical drone detection range, especially in the rear hemisphere.show more

[Discrete Fourier Transform] by Hand ✍️ In signal processing,... the Discrete Fourier Transform (DFT) is no doubt the most important method. But the math involved is extremely complex, literally, involving a summation over a complex number term e^(-iwt). I developed this exercise to demonstrate that underneath such complexity, DFT is just a series of matrix multiplications you can calculate by hand. ✍️ Once you see that, it should not surprise you that a deep neural network, which is also a series of matrix multiplications, with activation functions in-between, can learn to perform DFT to process and analyze signals so effectively. How does DFT work? [1] Given ↳ Signals A, B, and C in the 🟧 frequency domain: ◦ A = cos(w) + 2cos(2w) ◦ B = cos(w) + cos(3w) + cos(4w) ◦ C = -cos(2w) + cos(3w) ◦ Each signal is a weighed sum of four cosine waves at frequencies 1w, 2w, 3w, and 4w. ◦ We will apply Inverse DFT to convert the signals to time domain representations, and then demonstrate DFT can convert back to their original frequency domain representations. ↳ Signal X in the 🟩 time domain. X is sampled at 10 time points 1t, 2t, …, 10t: ◦ X = [-2.5, -1.8, 3, -0.7, -1.0, -0.7, 3, -1.8, -2.5, 5] ◦ Suppose X is also a weighted sum of the same four cosine waves, but we don’t already know their weights. We will apply DFT to discover them. [2] 🟧 Frequency Matrix (F) ↳ Write the coefficients of A, B, C as a matrix F. Each signal is a row. Each frequency is a column. ↳ A → [1, 2, 0, 0] ↳ B → [1, 0, 1, 1] ↳ C → [0, 1-, 1, 0] [3] Cosine → Discrete ↳ Sample from the continuous cosine waves at discrete time points 1t, 2t, 3t, to 10t. [4] Cosine Matrix (W) ↳ Write the samples as a matrix, Each frequency is a row. Each time point is a column. [5] Inverse DFT: 🟧 Frequency → 🟩 Time ↳ Multiply the frequency matrix F and the cosine matrix W. ↳ The meaning of this multiplication is to linearly combine the four cosine waves (rows in W) into time-domain signals (rows in T) using the weights specified in F. ↳ The result is matrix T, which are signals A, B, C converted to the time domain. Each signal is a row. Each time point is a column. [6] Transpose ↳ Transpose T, converting each signal’s time domain representation from a row to a column. [7] DFT: 🟩 Time → 🟧 Frequency ↳ Multiply the cosine matrix W with the transpose of matrix T. ↳ The purpose of this multiplication is to take a dot-product between each time-domain signal (columns in the transpose of T) and each cosine wave (rows in W), which has the effect of projecting the signal onto a cosine wave to determine how much they are correlated. Zero means not correlated at all. ↳ The result is an intermediate version of the “recovered” frequency matrix where each column corresponds to a signal and each row corresponds to a frequency. ↳ Compared to the original frequency matrix F, this intermediate matrix has non-zero weights in the correct places, but scaled up by a factor of 5 (n/2, n=10). For example, signal A, originally [1,2,0,0], is recovered at [5,10,0,0]. [8] Scale ↳ Multiply each value by 2/n = 1/5 to scale down the intermediate matrix to match the magnitude of the original frequency matrix F. [9] Transpose ↳ Transpose the recovered frequency matrix back to the same orientation of the original frequency matrix F. ↳ Like magic 🪄, the result is identical to the original F, which means DFT successfully recovered the frequency components of signals A, B, C. [10] Apply DFT to X: 🟩 Time → 🟧 Frequency ↳ Now that we have some confidence in DFT’s ability to recover frequency components, we apply DFT to X’s time-domain representation by multiplying W with X. ↳ The result is the an intermediate matrix. [11] Scale ↳ Similarly, we scale down by a factor of 5 to obtain the recovered frequency components of X (a column). [12] Transpose ↳ Similarly, we transpose the recovered column to row to match the orientation of the frequency matrix. ↳ Using the coefficients [0,0,3,2], we can write the equation of X as 3cos(3w) + 2cos(4w). Notes: I hope this by hand exercise helps you understand the essence of DFT. But there is more technical details, such as: • Sine: The complete DFT math also includes sine waves that follow a similar calculation process. • Phase: Here, we assume all the cosine waves are aligned at the origin, namely, phase is 0. If a phase p is added, for example, cos(w+p), we will need to calculate the sine component and use their ratio to figure out what p is. • Magnitude: If phase is not zero, the magnitude will need to be calculated by combining both cosine and sine terms.show more

New soul-finishing and lane-healing mechanics The reward system for... Troopers has been reworked. The first half of the souls still pops out as an orb that can be denied, but the second half is no longer given instantly to the nearest players. Instead, it drops to the ground as a sphere that must be picked up by approaching it. The pickup radius is 18 meters, and the orb will pull toward you as soon as you enter that radius. Only one player needs to collect it; the distribution rules remain the same. Trooper medics now drop a medic pack upon death. Its pickup mechanics (radius/duration) are identical to those of soul orbs on the ground. The medic pack heals all allies within 30 meters for 10% of their missing HP, plus 75 HP + 2 per minute of the match. #deadlockshow more

If order to hit a big league fastball your... brain needs to decide to pull the trigger roughly 25 feet from the ball reaching the plate…. In order to do that, your eyes must be oriented at a spot 25 feet to your left for a righty or 25 feet to your right if you are a lefty…. This begs the question what is the point of hitting off of a tee?…The body will never work the same vs a live ball…. Look how different Mike Trout looks when hitting off of a tee vs hitting a live ball…Watch his left arm and left shoulder do completely different things. The right forearm supinates vs an overhand pitch but it pronates vs the tee…. It’s a function of where the biceps inserts onto the radius. There isn’t a hitter on earth that will use the same swing mechanics off of a tee as they will vs an overhand pitch.show more
