Most Beautiful Graphs in Physics

9/6/2016

Every scientist knows that a nice looking figure can be very efficient in getting your paper published. A lot of NeuLog experiments generate really esthetic and interesting graphs. I gathered the top seven graphs for physics:

1. Simple Pendulum 

The location of a mass swinging back and forth on a thread was measured by a rotary motion sensor. Friction causes it to have slightly smaller amplitude each swing until decay.

2. Sound Waves  

When hit by a hammer, the tines of a tuning fork vibrate back and forth pushing the air molecules around them. When the tine moves forward the molecules are pushed together creating a compression and when the tine moves backward it creates a rarefaction (low pressure region). The compressions and rarefactions were detected by a sound sensor. This created a nice recurring pattern.

3. Sound Beats

In this experiment, two tuning forks with different frequencies were hit to create a stunning graph that demonstrated wave interference. Wave interference is a phenomenon which occurs when two waves meet while traveling along the same medium. When two waves interfere, the resulting displacement of the medium at any location is the algebraic sum of the displacements of the individual waves at that same location.

4. Thermal Conductivity

In this experiment, three different metals were heated and then cooled down. Their temperature was measured with the NeuLog Temperature sensor. The composition of the atoms in the material affects how the temperature changes.

5. Impulse and Momentum

In this experiment, a basketball was dropped on a force plate sensor. The graph shows the force that was applied on it. Impulse and change in momentum values were calculated using this great graph. The interesting thing about this experiment is that not only did the ball height decrease over time, but there was also less time between each bounce.

6. Magnetic Field

In this experiment, the magnetic field strength was measured at different locations on a bar magnet. This created a graph that has perfect rotational symmetry.

7. Charging a Capacitor

In this experiment, voltage and current were measured while a capacitor was charged and discharged. The current graph also has excellent rotational symmetry.

Deputy Editor of Physics Education, John Kinchin, prepared a review on NeuLog:

“Flexible data logging”

“Data logging has been around in schools for many years. Most data-loggers have functioned in similar forms, with connections via a serial port to a computer and onto a sensor or two. The new Edulogger claims to be the ‘simplest, fastest and most advanced system available’, so was it?”
“The computing centre of the suite of sensors is very flexible; any from a tablet, mobile phone or PC can be used as the computational core. The software is either a browser interface or on a PC can be a dedicated piece of software, which is similar in layout. The tablet software is very easy to use. Using a WiFi transmitter, the data can be streamed as part of its own network or integrated into an existing WiFi router. Using its own internal WiFi system is very easy; allow your tablet or computer to access the access point, open a browser and point it to the wifi201.com site and you are off. Once I had found out how to access the WiFi transmitter, the manual was redundant!”
The software   “Starting the software with the WiFi bridge in place opens up the welcome screen, which leads onto a screen with the modules installed on the left hand side and data being graphically displayed on the left. By clicking on the sensor icon, the software allows a customisable menu with access to recording times, number of points to be recorded per unit of time and triggers. This is a very impressive line up on a tablet computer.”
In conclusion….   “Overall I would certainly invest in this apparatus myself. The logging speed is indeed impressive as is the general layout of the logging screen and the clever use of a browser type interface.”

Light sensor brought to light          

05/26/2016   

One of the first sensors I worked with was the light sensor. It is amazing how this sensor can be used in so many fields of science. I started by creating experiments that teach the most basic principles of light.

The Light and Dark Colors experiment demonstrates the principle of light reflection and absorption. When visible light (that contain all the colors), completely reflects from an object, this light appears white. When the object completely absorbs all the light, it is recognized as black. This was done by projecting light on white, grey and black papers and measuring the reflected light.  One of the responses I received from teachers is that young students finally understood why it is not a good idea to wear a black shirt on a sunny day. 

Projecting Light on a white paper and measuring the reflected light.

The second experiment I want to tell you about is a really fun one, Colors of Light. In this experiment, you combine color filters and colored flashlights in order to detect the light coming through the filters. As an example, a red filter transmits (and reflects) mostly red light and absorbs the rest, while a blue filter does the same with blue color. So what will be the light intensity if we place a red filter on a blue flashlight? Conduct the experiment and you’ll see (and measure of course!).

At the end of the experiment, you will find some fun educational activities you can do with the colored flashlights and filters (those items are included in our Light kit).

What’s great about this sensor is that it has three different ranges of light intensity. This way, you can choose the best range according to your experiment. When measuring light outdoors I like to use the 0 to 150,000 lx range (like in the Rayleigh Scattering experiment). When I measure light in a dim room (like in the Light and Shadow experiment) I use the 0 to 1000 lx range. For the rest of the experiments I use the middle range (0 to 6000 lx).

Sensors that work great along with this sensor:
• UVA
• UVB
• Temperature
