NEW YORK, NY, September 18, 2014 – Momentum today announced that it has entered into a joint business arrangement with Rightside Group to provide marketing support, premium names, and registrar reseller services for two of Rightside’s new top level domains (TLDs) - .LAWYER and .ATTORNEY.

With the .LAWYER or .ATTORNEY domain name extensions, lawyers, legal firms, law students,and peopleinvolved in legal services can now create a unique, lasting, and immediately identifiableweb presence.   Lawyers will be able to brand their websites, establish brandable bio pages, setup brandable .LAWYER and .ATTORNEYemail addresses, and redirect users from new URLs ending in .ATTORNEY or .LAWYER to their existing websites.

The new .LAWYER and .ATTORNEY domain extensions are currently in the Pre-Registration phase, which means it is already possible for professionals to express interest in securing or  General Availability is scheduled for October 8th and initial demand is expected to be high as legal professionals race to secure the web addresses that best identify their specialties.

Jeffrey Weisel, an attorney said that having his own site ending in .ATTORNEY would allow him to control his web presence no matter what path his career took. “I could redirect JeffWeisel.Attorney to my company website, or if I ever return to a law firm, I can easily point it to my bio page. I will now have complete control over the number one way potential clients and employers are finding legal professionals such as myself.”

.LAWYER and .ATTORNEY domain names will cost as little as $35 and interested parties can check availability of their preferred name at

Momentum and Rightside are planning a series of events, educational activities, and marketing promotions to coincide with the availability of the new.LAWYER and .ATTORNEY domains.

Momentum also plans to deploy .LAWYER and .ATTORNEY street teams near the offices of many top NYC law firms and law schools around the dates of general availability in order to raise awareness within the legal community. 

Matt Godson, Co-CEO with Momentum, remarked, “We are expecting a large number of attorneys to secure around the time of general availability, but we are also seeing some early interest from our contacts in the legal community in obtaining URLs that match up with distinct practice areas, such as and It will be interesting to see which law firms are ahead of the curve and snap up some of the more coveted terms.”

Dwayne Walker, Senior Vice President with Rightside, remarked, “Momentum, through their marketing, distribution, and consulting services, understands both domain branding and the legal space, which makes partnering with them a natural fit as we prepare for the release of .LAWYER and .ATTORNEY.”

More details on general name availability can be found at  Additionally, information on high-value premium .ATTORNEY and .LAWYERdomains can be obtained by contacting Matt Godson at

Is it possible to describe billiards in the unit square (see for info) in terms of events and if? For example, let the dynamical system
{x''(t)=0,y''(t)=0, x(0)=0.5, x'(0)=0.2, y(0)=0.5, y'(0)= sqrt(3)/5}
be given, where the trajectory [x(t), y(t)] satisfies the usual laws of reflection when reaching the boundary {x=0}, {x=1}, {y=0}, {y=1}. The same question about billiards in the unit disk.

I  have a system of second order differential equation to be solved numerically. I would like to set up events to halt integration  to find the values of phi when r(phi)=2/3 . Here is my code




The code only works for the second event so it halts for r(phi)=1.63... etc

How do i stop this?


Thanks for any help.

My problem is How to use events command in dsolve/numeric for different points of independent variable?                                     A simple example:


ds:=dsolve({de,x(0)=1}, numeric, method = rkf45,abserr=1E-12,relerr=1E-11,events =[[x(t)-1E-8,halt]]);

works perfectly, but I need to compare x(t) and x(t-h) in two consecutive...

ODE with events...

HI,is it possible to solve the ODE system (that I have uploaded) by adding events at a certain timestep, instead of reformulating the system for each step.The ODE system expresses two coupled movements y(t) and X(t). The current position of y(t) is controlled by a parameter which depends on values calculated in the previous step, while changing the sign for each step.Thank you! 


     So I've got a numerical solution to a D.E. and want to find which parameters (v, theta) cause the second event to occur. Here's my dsolve

> soln:= dsolve({eqx, eqy, inty, intx, x(0)=0, y(0)=0}, {x(t), y(t)}, numeric, method = rkf45, output=listprocedure, parameters=[v, theta], events=[ [ [diff(y(t),t)=0, y(t)

 The first event is "Does the trajectory reach its max at a height less than 3.05m? If so, stop computation"...


I have the same problem.

   "Simulation problem: maximum number of event iterations reached (100) at t= ...."

I have a model which worked without problem in maplesim2, using a lot of event iterations. The model can only work this way, becouse its a mechanic model where the friction is function of the sliding speed, thus where the speed changes value, the friction coefficient does also, and an event occurs.

I really need to know where...

What is meant by events? I have seen this error numerous times.

   "Simulation problem: maximum number of event iterations reached (100) at t= ...."

How do I model so that I can avoid them?

My question is related to this discussion on "querying events"

I thought I might start a new thread.

The following loop is an illustration of the sort of thing I'd like to do with dsolve and events: I loop over a parameter of the "event" and extract information on the solution at different values of the parameter. Here is the code (successfully tested on Maple 15 / Standard / Windows)...

I have a system of 3 ODEs in 3 variables x(t),y(t),z(t) to be solved numerically. I would like to set up events to halt integration as soon as one of the derivatives changes sign.

I've tried things like:

'events' = [ [ diff(x(t),t) >0, 'halt'] ] :

'events' = [ [ diff(x(t),t) = 0 .. 0.1, 'halt'] ] :

I might have tried something like increasing(x(t)) (how nice and intuitive), but if I understand correctly the help page on this, increasing(x(t)...

And so with this provocative title, "pushing dsolve to its limits" I want to share some difficulties I've been having in doing just that. I'm looking at a dynamic system of 3 ODEs. The system has a continuum of stationary points along a line. For each point on the line, there exist a stable (center) manifold, also a line, such that the point may be approached from both directions. However, simulating the converging trajectory has proven difficult.

I have simulated as...

dsolve event handling looks like a great tool, but I can't understand how it works and it's not sufficiently popular to google my way to examples online. There are two things I'd like to do: 1) interrupt the computation once some variable leaves a certain range, 2) interrupt the computation if the solver gets stuck into an infinite loop. Both are documented in the help, but I don't understand it. Suggestions welcome, thanks!


I made an upgrade from Maple 13 to 14, but a program i wrote with maple 13 (ode event handling) simply is incorrect in maple 14. The events aren't recognized anymore. What is the problem?

Thank You.


I i have a 2nd order ODE where i want to chance the derivatives of x(t) and y(t) exactly at sqrt(x(t)^2+y(t)^2)=1 ,or before, as close to 1 as possible.

I found "event=" in/dsolve/numeric/events, where i can define the trigger and the action.

What is the difference between: "event=[[sqrt(...)-1,diff(x(t),t)=...],[sqrt(...)-1,diff(y(t),t)=...]]" and "event=[[sqrt(...)-1,[diff(x(t),t)=...,diff(y(t),t)=...]]]", because i get different results, which one is the correct form?
