Hi everyone I am using Visual Studio Code with Node.js 18.17.1. I installed Puppeteer 22.5.0 with the following command: Npm install browserify -g I tried creating a bundle with the following command: Browserify index.js -o bundle.js This error message came up: Error: Can't walk...

Here is an open access review of visual processing in the fruitfly nervous system. It will give you an overview of what is known about how the nervous system extracts relevant information from its visual inputs. Fruit flies (Drosophila) are a very tractable research organism in which...

Hi, Are the any documented examples of descriptions of a subject's sensations during stimulation of the visual cortex, when given by people born blind? This is something I am curious about after hearing a creative musical piece sung by a disabled child. I am assuming that many people born...

Hi Everyone, I could use some help in SolidWorks, when I go to sketch geometry, the software creates a lot of lines that extend off the starting point and they don't go away until I snap back to the starting point. I have an image attached to show what is happening. This creates a problem...

Hi PF! I am running VS Code for python on Ubuntu. Is there a way to execute a specific python line? As I currently have it set up, on the terminal input at the bottom of the screen, I can only work through the terminal, so a command like print('hello world') won't do anything. THanks so mcuh!

Summary:: I am in the highest level Quantum class at my university- technically considered a grad class. I am an undergrad and need advice on just how to learn it. What study tips? Good Youtubers? Physical simulations? Anything that helped you in quantum mechanics. Hello! I am an undergrad...

I tried resetting the PC and reinstalling visual studio code and that does nothing. Any advice would be helpful.

I have been tasked by my fluid dynamics professor to create a 3 minute video showing and explaining laminar flow vs turbulant flow. It must be engaging and explain the concepts simply enough with no math. I will be re-writting this definition below to suite the needs ""Laminar flow occurs...

I have been using Visual Studio Code for a couple months now and it has been fine. When I want to run some code, there is usually a little green triangle button in the top right corner that I can click on. A few days ago, that triangle turned white only for Python files (it is still green for...

In recent years, I found that many cars, I don't know if their headlamps are original or customized, the light is very bright or sharp, sometimes causing me to see temporary shadow in the eye like camera flash or even a little bit faint. In addition to yellow and white light there are also many...

When we hear the word storm, we think of the threats that it brings and the damage it might leave behind. I like this video, because it shows the spectacular sky shows that come with storms. They are surely one of our most magnificent displays of nature.

The attached diagram shows the cathode rays moving in straight lines forward but the anode is beneath them?

A regulation NFL playing field of length x and width y has a perimeter of 346_2/3 or 1040/3 yards. (a) Draw a rectangle that gives a visual representation of the problem. Use the specified variables to label the sides of the rectangle. (b) Show that the width of the rectangle is y = (520/3)...

The 2 Bowling Balls Ball(a) & Ball(b) (a) is in acceleration of 10m/s^2 (b) is in at fixed position in a gravitational field where g=10m/s^2 In both cases the observer is: - perpendicular to the vector of acceleration - distant enough to be in empty flat space Question : In an instantaneous...

Hello people :oldsmile: I would like to discuss one issue here. Let’s imagine that I am looking to the sphere: I can clearly see that it sphere, not cylinder, or cube, or submarine, or dinosaur. So what I see is objective truth. But how do we generally see the objects? We have got two eyes...

Hi everyone! We launched Connected Papers 7 months ago, with the goal to help researchers visually find and explore academic papers. Input: a paper of your liking. Output: a full interactive graph of similar papers to explore. For example, here is the graph for The Coevolution of Galaxies and...

This is a very simple program about Class with Inventory.h, Inventory.cpp and source.cpp. I reduced to very simple just displaying two message and it just won't build. It gave me error message I don't follow even after reading the error code online. I follow the example and syntax from the book...

I am having an error setting up mern https://www.digitalocean.com/community/tutorials/getting-started-with-the-mern-stack#testing-api I have to assume I didn't follow the instruction properly.The error is under Database section from the link above. When I type require('dotenv').config() into...

This is surreal!

I had Python 3.7.3 installed on my laptop. I decided to upgrade to 3.8.0, and after installing all necessary packages, uninstall the old version. The installation of 3.8.0 was successfully done. With pip, I installed scipy, numpy and sympy. Now when I tried to install matplotlib, it threw an...

Let's say you have a 4 digit "odometer" using just the digits 0 through 7. So it starts at 0000 and works its way up to 7777. So, for example, the next reading after 0007 is 0010 etc. There are ##8^4 = 4096## readings before it rolls over. I want to create and initialize an array with ##4096##...

The brain receives a lot of visual information some of which is redundant visual information. I am imagining it like the brain receiving a 1000 pixel wide by 1000 tall image of a road. The brain has received 1,000,000 bits/pixels of information. I am assuming the brain doesn't need all that...

Is there a way to generate an accurate visual computer simulation of gravitational lensing?

Dear Forum Members, I need to create and use dynamic-link library (DLL) for Fortran application using Compaq Visual Fortran 6.6. The following code works just fine: ########################################### PROGRAM AMAIN1 IMPLICIT NONE REAL(8):: A,B,S A = 1D0 B = 2D0 CALL SUBRO1(A,B,S)...

I am collecting ways to visualize the curvature of spacetime -- and movement of objects affected by gravity -- as per Einstein's GR. Alternatives to the bowling ball / trampoline image so often used in the popular press. Images that show the similarities / differences between Newton & Einstein...

I have an exercise: A distant camera snaps a photograph of a speeding bullet (speed v) with length b in its rest frame. Behind the bullet and parallel to its path is a meter stick, at rest with respect to the camera. The direction to the camera is an angle $\alpha$ from the direction of the...

I will take Intro to C programming this semester and can I use MVS for coding C ?

Hello all! I am trying to make a VISUAL model (in C#) to predict lunar and Earth eclipse periods for a satellite that I have accurate ephemeris for. I want to calculate everything in ECEF reference frame. How would a go about modeling this system to the accuracy I'm interested in? I assume I...

According to a paper published back in March, humans see the world with a much higher visual acuity compared to other animals. Cats, for example, have roughly 1/6th the visual acuity of humans, and fruit flies have roughly 1/100th. A few animals do better than ourselves, namely eagles, hawks...

How do I call a website(by user input) so I can make a query in visual basic

preferably free :biggrin: I used Prezi in high school and PowerPoint in middle, but haven't had to use anything since. thanks. edited to add: if it's a really great one...I would be willing to look into buying it.

Hi, Can someone please anlayse the visual effects for light travel in the documentary 'Journey to edge of the universe' Especially around the 43:12 and the 1:02:20 mark. Can you also tell me if it is or is not an accurate depiction of what we should be seeing theoretically?

I've often wondered at the "resolution" of the human visual system but it's not at all clear from what I've read whether this question even makes sense. As a sort of general position, many of the articles I've read suggest that the human eye, over the full field of vision, delivers around...

Dear moderator, if the thread is irrelevant to this forum section, please move it to the right section. Thanks.

Do all humans have the same visual processing speed or does it differ from person to person? By ‘visual processing speed’, I mean the speed at which one takes to process visual information. For example, if a light has a frequency of 50 hertz where it switches on / off 50 times a second, do all...

I am not sure of the right group for my question.Medical seems like a place to start. ---- I am monocular with an advancing cataract and macular pucker. Glasses with a corrective plastic lens help me see somewhat better. A pair of tinted No IR UV shields in front of the glasses sharpens my...

Hi, I'm looking for a visual proof log(ab) = log a + log b I've seen diagrams where the values are measured out, but it's not immediately obvious why this holds. Is there an intuitive way to illustrate this? Also, are there other functions with this property.

From what I have understood about Pearson correlation coefficient I have created a visual illustration, I would like to know if this understanding looks correct. Say I have a sample with 5 data points:- x y 8 6 16 8 20 16 28 12 32 20 My goal is to...

Is there a good way to think about the namespace/object/class/method paradigm when transitionig from non OOP C programming to Visual C# programmig? I've written Tcl/Tk GUI apps for manufacturing test fixtures in the past, but now I need to interface with multiple VISA instruments with National...

Hi, this is a newbee question. Does the Fundamental Theorem of Calculus supply a visual (graphical) way of linking a function (F(x)) with its derivative (f(x))? That is, the two-dimensional area under a curve in [a,b] for f(x) is always equals to the one-dimensional distance F(b)-F(a)? If...

There's lots of other questions on the forum about 2 black holes, but I think this is different - and I can't get my head around which outcome is consistent with GR. Black holes here are simplistic - non-rotating and let's assume with a tiny accretion disk; just enough grains of matter to allow...

To think something with full concentration I close my eyes. I believe many people also do it. It seemed to work and generates good thoughtful results. May be because with eyes closed brain is free to handle the billions of photons coming from eyes. In a noise-free room concentration should be...

why addition of two vectors are represented by this diagram, why the sum of two vectors are between both the vectors. Does it takes the idea of hitting a ball , if we hit a ball to its left side it goes right side and when hitted to its right side it goes left side and when we hit...

Hi, this may seem like an odd questions to most of you but I'd still like to ask what could be some visual proofs of being at high altitude, say 10,000 feet above sea level. While any said proof is not extremely rigorous or untamperable and probably little more than a showy capture to add to...

Hey guys so I just came across visual studio 2015 to program some real time voltage chart. I don't have enough knowledge of this software as I have been working with visual basic 6 before until I had to let it go for good. The issue is I cant´see the chart I'm creating I'm using the default...

Allo, I have got VSC and have been using it for JavaScript in Unity. Also, I am new to VSC. However, I have been wanting to use it for writing C and C++ for just standard compiling and executing. Is there some way to run '.c' Visual Studio Code in, let's say, on command prompt. I have heard I...

Homework Statement First of all, I used the Window xp & Compaq Visual Fortran 6.6 installed in VMware workstation. In my case, there are no compile and link errors in source code, and excuting that program is also done. But I want to generate 300 random numbers by using my program (Log-normally...

I have the following code which doesn't get compiled: using System; using System.Collections; namespace ConsoleApplication5 { static void Main(string[] args) { class Program { public class Animal { public virtual void Greet() {...

I am reading the book "A History Of Optics" by Oliver Darrigol, and I came across this sentence (under the heading Visual Fire): Isn't this a low-quality argument? This can be directly disproved by the fact that humans inbabilty to see in dark, viz. if humans can see things from the "fire"...

I'm a biologist interested in physics. Biology is undergoing several revolutionary changes, but physics is interesting too! I am interested in the physical aspects of information processing in biological entities, things like: genetic control systems, information transmission through...
