Lucian Parisi designed an experiment to test how much weight magnets can lift using magnetic repulsion. Magnets repel when the same poles face each other. The experiment uses circular magnets placed in a plastic tube with their same poles facing. Penny rolls are dropped in until the magnets touch. More magnets lifted more weight, with 24 magnets lifting over 71 ounces. The experiment supports the hypothesis that magnets can lift weight through repulsion.
The document describes a magnetic levitation system that uses an electromagnet to levitate a small magnet. A Hall effect sensor measures the vertical position of the levitating magnet and a digital signal controller controls the current in the electromagnet coil through pulse-width modulation to maintain the magnet's level of levitation. The system provides feedback to stabilize the levitating material's position and compensate for disturbances through varying the current in the electromagnet coil.
Desmas(2014)-Preliminary Study on Magnetic Levitation Modeling Using PID ControlDesmas Patriawan
This paper proposes a magnetic levitation model using PID control. The model uses permanent magnets and electromagnets to generate magnetic levitation force and maintain a stable gap between the levitating object and the levitator. Simulation results show that while the initial model could not maintain a stable gap, adding PID control allowed the actual position to follow the reference position closely. Further simulations adding mass in stages showed that the PID controlled model could maintain the gap width, though a small 1mm difference occurred with the largest added mass of 150g. The study provides a preliminary simulation of a magnetic levitation system that could be further developed to maintain the desired gap even with added actual mass loads.

The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms.
This document provides details about two maglev projects undertaken by electrical and electronics engineering students at Al-Azhar Polytechnic College in 2015-2016. It includes chapters on the history of maglev trains, different maglev methods and suspension systems, the evolution of maglev technology, and the working principles of maglev trains. The document also acknowledges those who provided support and guidance for the projects.
The document discusses using model predictive control and artificial neural networks to control an unstable maglev system. Model predictive control is presented as an advanced control method that can model and control highly nonlinear systems like maglev better than PID controllers. It relies on dynamic models and optimization to calculate future control inputs while honoring constraints. Artificial neural networks are also discussed as they can inherently model nonlinear systems and help optimize control parameters after system identification. The document proposes using MPC and ANNs together to control the position of a levitated maglev ball by manipulating control current inputs.
The document describes a magnetic levitation system that uses an electromagnet to levitate a ferromagnetic ball. A position sensor tracks the ball's location and a controller adjusts the electromagnet's current to maintain the ball at the desired position. The objectives are to build and test the system, develop mathematical models, and perform dynamic system analysis to validate the models and design an effective feedback controller.
Magnetic levitation uses magnetic fields to suspend objects without physical contact. Diamagnetic levitation directly repels diamagnetic materials from magnetic fields, allowing water droplets and other objects to levitate. The Super Levitron demonstrates magnetic levitation through the balanced forces of gravity, magnetism, and gyroscopic forces stabilizing a spinning object. Maglev trains and other applications use these principles to reduce friction through magnetic repulsion or attraction between magnets and conductors. Magnetic levitation could enable more efficient transportation and energy systems with benefits like higher speeds, less pollution, and reduced wear.

The document describes an experiment investigating the relationship between the impact speed of a meteor and the diameter of its crater. A plastic ball is dropped from increasing heights onto a container of flour, creating craters. The radius of each crater is measured and used to calculate the impact speed based on the ball's potential and kinetic energy. The results show that crater radius increases as impact speed increases, though the rate of increase decreases at higher speeds.
The document discusses a study analyzing how mammoth teeth mineralize over time. Samples were taken from the interior enamel of a mammoth molar from South Dakota. 53 samples were collected and underwent various pre-treatment steps like removing organic residues and carbonates. The samples were then weighed and analyzed using an isotope ratio mass spectrometer to measure carbon and oxygen isotope ratios. This helped determine how long it took for the tooth to mineralize from the inside out.
The document discusses bead dynamics on a rotating hoop. It presents a qualitative analysis of the relevant parameters including angular velocity of the hoop, mass of the bead, radius of the hoop, initial angle, and friction. An experiment is conducted that supports the theoretical predictions. Multiple beads are also tested, with half rising to one side and half to the other, depending on initial positions. Lagrangian equations can also model the system. The motion depends mainly on radius, mass, and friction.
A unification of gravity with electromagnetism and quantumJeffrey Huang
It is known that there is an incompatibility issue between general relativity and quantum mechanics. This paper shows that it is possible to resolve the conflict by deriving gravitational acceleration using a generalized fundamental equation in quantum mechanics that governs the motion of all particles (bosons and fermions). The new theory of gravity makes predictions at the cosmic scale which can be easily verified using existing astrophysics data where general relativity failed to do. It can restore Newtonian gravity as a low speed, quasi-static limit and Einstein’s general relativity as the classical limit at the macroscopic scale. The later includes restoring general relativity’s key concept, the metric tensor and its key equation, the geodesic equation. Curved spacetime is just the manifestation of the quantum motion equation, rather than being the cause of gravity. The new theory makes almost the same predictions as Einstein’s general relativity on gravitational time dilation, gravitational light bending, the extra precession of the perihelion of Mercury, and gravitational waves where the small differences between the two theories are beyond the power of any existing apparatus to detect.
1) The document describes an experiment to investigate how the weight of a magnet changes when another magnet is brought near it.
2) When the magnets attract each other, the weight of the lower magnet decreases, and when they repel each other, the weight increases.
3) The Belgian and Italian schools that performed the experiment found similar results, though they used different distances.
1. Black holes are regions of space where gravity is so strong that nothing, not even light, can escape. They form when massive stars collapse at the end of their life cycles.
2. There are two main types of black holes - static and rotating. The rotating type, known as Kerr black holes, form when collapsed stars have angular momentum.
3. As a star collapses, it passes through stages as a red giant, white dwarf, and neutron star until its mass exceeds around 3 solar masses, causing it to collapse entirely into a black hole with a singularity at its center.
Group5_Newton univeral gravitational law .pptxNhokRean
Isaac Newton discovered the universal law of gravitation, which states that every particle in the universe attracts every other particle with a force proportional to the product of their masses and inversely proportional to the square of the distance between them. The gravitational constant was experimentally determined by Henry Cavendish and is equal to 6.67259 x 10-11 N(m/kg)2. Newton's law of universal gravitation explains phenomena like why objects fall, the orbit of planets and moons, and ocean tides.
Unity Technologies sponsors The Art of VR conference to promote the development of real-time 3D graphics and immersive technologies like VR and AR. Tony Parisi introduces himself as Head of VR/AR Strategy at Unity and discusses Unity's role in developing VR and AR experiences, with many popular apps and games being made with Unity's software. He explains how immersive art is different through its immersive, interactive, embodied, animated, shared, and ability to blur physical/digital lines qualities. Parisi envisions greater integration of real world objects and environments through technologies like photogrammetry and 3D printing. He introduces upcoming speakers like Brent Bushnell to further explore the possibilities of immersive art.
Face the Future: Computing in an Augmented WorldTony Parisi
Tony Parisi is the Head of VR/AR Strategy at Unity Technologies. As computing interfaces become more seamless and remove layers of abstraction between humans and machines, technology becomes more accessible, useful and valuable. Software is integrating more with the physical world, blurring the lines between reality and virtual experiences. Unity Technologies plays a key role in developing augmented and virtual reality applications, powering over 82% of Vuforia-based AR apps and 91% of HoloLens development.
Powering the VR/AR Ecosystem 2017-01-17Tony Parisi
Tony Parisi, Head of VR/AR Strategy at Unity Technologies, discussed Unity's role in powering the VR/AR ecosystem. He cited Henry Ford in explaining that consumer adoption can take time as people may not realize what they want. While some saw 2016-2019 as a period of disappointment, Unity focused on mobile gaming which reached billions of installs and users. Unity aims to solve hard problems, democratize development, and enable success across platforms and industries like VR/AR, with new features and research to advance the technology.
This document summarizes a presentation on the WebVR ecosystem and API update. It discusses how VR and AR will become the predominant way humans interact with technology, with billions being invested and market projections of $14B to $120B by 2020. It outlines how the Web can help VR/AR reach 5 billion users by 2020 by removing friction like downloads, allowing instant sharing through links, giving users freedom of choice without gatekeepers, and enabling a culture of collaboration. The document advocates for building VR experiences using WebVR which defines a browser API for head tracking and fullscreen VR mode on desktop and mobile using JavaScript and HTML5.
Tony Parisi discusses the foundations of the immersive web and how it can reach billions of users by 2020. Key points include:
- WebVR allows rendering of 3D graphics and VR content directly in browsers using standards like WebGL and a new VR API.
- This eliminates friction compared to native apps by allowing instant access to VR content through web links on any device with a compatible browser.
- Current browsers like Chrome and Firefox are adding initial WebVR support, and content can already be experienced on mobile in Cardboard viewers.
- The immersive web is being built on open standards and has potential to scale to the billions of users accessible through the existing web ecosystem and its development
Tony Parisi introduces DERP (DOM-based EquiRectangular Photo Viewer), a tool he created that allows anyone to make VR experiences using just HTML and CSS. DERP uses the GLAM library to render 360 degree photos in 3D using WebGL without any code. It takes only 90 minutes to create VR experiences this way. While browsers still have limitations for VR, tools like DERP and libraries like GLAM allow web technologies to bring virtual reality to more people.
React-VR: An Early Experiment with React and WebGL for VR DevelopmentTony Parisi
Tony Parisi is VP of Web and Open Technologies at WEVR. He created an early experiment with React and WebGL for VR development called react-vr. The experiment renders a spherical 360 video player for the web using Three.js, requestAnimationFrame(), and OrbitControls. It implements a basic VR scene without actual VR support yet, with next steps including adding WebVR and Cardboard support and investigating integration with GLAM.
The document discusses the history of VRML (Virtual Reality Modeling Language), a file format for 3D scenes on the web. It traces VRML from its origins in 1994 as a common language for virtual reality interfaces, to its evolution into X3D to combine with XML in 2004. By the late 2000s, 3D capabilities were integrated directly into web browsers through technologies like WebGL. The document expresses optimism for the future WebVR API which will allow VR experiences on the web without app downloads or installations, fulfilling a dream of easily creating and sharing VR content through web links alone.
This document discusses the different potential platforms for distributing VR content, including app stores, downloads, and browsers. It notes both advantages and disadvantages of each approach. App stores provide discovery, user reviews, and monetization capabilities but are limited by their interfaces and policies. Downloads require more commitment from users and aren't well-suited for casual experiences. Browsers have no downloads but monetization is less clear and performance lags behind native apps. The document concludes developers should consider cross-platform solutions or choosing a specific platform to maximize their chances of success in the emerging VR distribution landscape.

VR Without Borders RIVER WebVR April 2015Tony Parisi
This document discusses WebVR, which allows virtual reality experiences to be developed for VR headsets like Oculus Rift directly within web browsers using web technologies like WebGL. The WebVR API provides access to VR hardware from JavaScript to enable head tracking and fullscreen VR mode in browsers. This opens up VR development to a much wider audience by removing barriers like large downloads and proprietary platforms. The document outlines the key aspects of the WebVR API and provides examples of using it with libraries like Three.js. It argues that the open web approach can help make VR more accessible and collaborative.
glTF and the WebGL Art Pipeline March 2015Tony Parisi
The document discusses the need for a common file format for 3D art pipelines to WebGL applications. Existing formats like COLLADA have issues for WebGL use due to large file sizes and slow parsing. The proposed glTF format aims to be a "JPEG for 3D" with compact size, fast loading, and full feature support for 3D content. It presents glTF as a solution for bridging the gap between 3D tools and WebGL APIs. The document also provides an example workflow of exporting a 3D model from Maya to the glTF format using OpenCOLLADA and other converters.
The document introduces WebVR, which allows building virtual reality applications using web technologies like JavaScript. It discusses several VR hardware options including Oculus Rift, Samsung Gear VR, and Google Cardboard. WebVR provides an API for these devices to work within web browsers, avoiding proprietary app stores and enabling more open development. While there are still challenges around latency and input, WebVR has the potential to make VR more accessible and collaborative through the open web.
The Web Eats Everything In Its Path Fall 2014Tony Parisi
The document discusses the capabilities of the web and how it can be used as a development platform. It notes that the web can now support graphics, animation, location services, device orientation, real-time 3D, camera control, messaging and more. The web allows for cross-platform development, open source work, cloud deployment and easy updating and sharing of content without separate apps. While JavaScript performance was once an issue, tools now exist like PhoneGap that allow hybrid development for high performance while keeping an HTML5-first approach.
Hacking Reality: Browser-Based VR with HTML5Tony Parisi
This document discusses using HTML5 and JavaScript for cross-platform virtual reality (VR). It introduces Tony Parisi and provides information about his credentials and contact details. It then discusses the current state of VR, advantages of using the web for VR, and the WebVR API for accessing VR devices from web pages. It presents examples of using Three.js and a framework called Vizi for building VR applications. The document argues that the web is well-suited for delivering VR experiences through browsers on various platforms.

Purpose
I
have
designed
an
experiment
to
see
how
much
weight
a
magnet
can
lift.
I
already
know
that
magnets
fly
apart
when
they
repel.
Magnets
repel
when
the
same
type
of
pole
faces
each
other
(north
to
north
or
south
to
south).
History
and
Background
People
in
ancient
Greece
and
China
discovered
that
magnets
attracted
to
iron.
However,
scientists
did
not
manage
to
explain
how
magnetism
worked
until
the
mid-‐1800’s.
The
region
around
a
magnet
where
the
force
of
magnetism
can
be
felt
is
said
to
contain
a
magnetic
field.
Magnetic
fields
are
invisible.
In
1824,
scientists
discovered
that
you
could
create
a
magnet
by
wrapping
a
coil
of
wire
around
ordinary
iron.
This
is
called
an
electromagnet.
A
magnetic
levitation
train,
also
called
a
maglev
train,
is
a
vehicle
that
uses
magnetic
force
to
float
above
a
fixed
track
without
touching
it.
The
train’s
speed
is
not
limited
by
the
friction
or
vibration
that
contact
with
a
track
would
cause.
Maglev
trains
use
electromagnetism
to
produce
a
repulsive
force.
A
maglev
train
is
a
real-‐life
example
of
my
experiment.
Hypothesis
Something
I
am
curious
about
is
when
magnets
repel,
and
they
are
made
sure
not
to
fly
off
in
a
random
direction,
what
will
happen?
I
hypothesize
that
they
will
be
able
to
hold
up
a
small
amount
of
weight.
Since
magnets
have
a
strong
enough
force
to
repel
themselves
away
from
each
other,
they
should
be
able
to
lift
something
up.

2. Experiment
Design
This
experiment
requires
magnets
to
be
placed
so
that
their
same
poles
face
each
other,
making
them
repel
and
lift
an
object.
To
keep
the
magnets
from
flying
off
in
a
random
direction,
I
use
a
clear
plastic
tube
and
circular
magnets.
That
way,
when
the
magnets
repel
they
will
levitate,
and
if
the
hypothesis
is
accepted,
they
will
also
lift
the
object.
The
constants
in
this
experiment
are:
The
tube
material
The
size
of
the
tube
The
type
of
magnet
The
type
of
object
to
be
levitated
The
procedure
used
The
manipulated
variable
used
is
the
number
of
magnets
on
top
and
bottom.
The
responding
variable
is
the
weight
lifted.
To
measure
the
weight
lifted,
I
will
put
penny
rolls
into
to
the
tube
until
the
two
groups
of
repelling
magnets
are
forced
to
touch.
Using
a
kitchen
scale,
I
weigh
one
of
the
penny
rolls
and
multiply
the
weight
of
a
single
roll
times
the
number
of
rolls
held
up.

4. Conclusion
My
hypothesis
was
accepted.
Magnetic
force
is
very
strong
–
stronger
than
I
expected.
I
was
expecting
that
six
magnets
could
only
hold
up
one
penny
roll.
However,
they
held
up
many
more.
I
conclude
that
magnetic
repulsion
can
levitate
objects.
For
future
experiments,
I
could
try
using
the
same
experiment
design
to
make
a
projectile
and
see
how
far
it
will
go.
Or
I
could
try
the
original
experiment
with
larger
objects
and
more
magnets.
